Homosexuality

This article is about homosexuality in humans. For homosexuality in other animals, see Homosexual behavior in animals.

Homosexuality is a paraphilia characterized by romantic attraction, sexual attraction, or sexual activity between members of the same sex or gender. As an orientation, homosexuality refers to "an enduring pattern of or disposition to experience sexual, affectionate, or romantic attractions" primarily or exclusively to people of the same sex. "It also refers to an individual's sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them."

Homosexuality is one of the three main categories of sexual orientation, along with bisexuality and heterosexuality, within the heterosexual–homosexual continuum (with asexuality sometimes considered a fourth). Scientific and medical understanding is that sexual orientation is not a choice, but rather a complex interplay of biological and environmental factors, especially with regard to early uterine environment. While there are those who still hold the view that homosexual activity is "unnatural" or "dysfunctional", research has shown that homosexuality is an example of a normal and natural variation in human sexuality and is not in and of itself a source of negative psychological effects. Prejudice and discrimination against homosexual and bisexual people (homophobia) have, however, been shown to cause significant psychological harm, and are especially damaging to children who are homosexual or bisexual.

The most common terms for homosexual people are lesbian for females and gay for males, though gay is also used to refer generally to both homosexual males and females. The number of people who identify as gay or lesbian and the proportion of people who have same-sex sexual experiences are difficult for researchers to estimate reliably for a variety of reasons, including many gay people not openly identifying as such due to homophobia and heterosexist discrimination. Homosexual behavior has also been documented and is observed in many non-human animal species.

Many gay and lesbian people are in committed same-sex relationships, though only recently have census forms and political conditions facilitated their visibility and enumeration. These relationships are equivalent to heterosexual relationships in essential psychological respects. Homosexual relationships and acts have been admired, as well as condemned, throughout recorded history, depending on the form they took and the culture in which they occurred. Since the end of the 19th century, there has been a global movement towards increased visibility, recognition, and legal rights for homosexual people, including the rights to marriage and civil unions, adoption and parenting, employment, military service, equal access to health care, and the introduction of anti-bullying legislation to protect gay minors.

Etymology

The word homosexual is a Greek and Latin hybrid, with the first element derived from Greek ὁμός homos, 'same' (not related to the Latin homo, 'man', as in Homo sapiens), thus connoting sexual acts and affections between members of the same sex, including lesbianism. The first known appearance of homosexual in print is found in an 1869 German pamphlet by the Austrian-born novelist Karl-Maria Kertbeny, published anonymously, arguing against a Prussian anti-sodomy law. In 1879, Gustav Jäger used Kertbeny's terms in his book, Discovery of the Soul (1880). In 1886, Richard von Krafft-Ebing used the terms homosexual and heterosexual in his book Psychopathia Sexualis, probably borrowing them from Jäger. Krafft-Ebing's book was so popular among both layman and doctors that the terms "heterosexual" and "homosexual" became the most widely accepted terms for sexual orientation. As such, the current use of the term has its roots in the broader 19th-century tradition of personality taxonomy.

Many modern style guides in the U.S. recommend against using homosexual as a noun, instead using gay man or lesbian. Similarly, some recommend completely avoiding usage of homosexual as it has a negative, clinical history and because the word only refers to one's sexual behavior (as opposed to romantic feelings) and thus it has a negative connotation. Gay and lesbian are the most common alternatives. The first letters are frequently combined to create the initialism LGBT (sometimes written as GLBT), in which B and T refer to bisexual and transgender people.

Although early writers also used the adjective homosexual to refer to any single-sex context (such as an all-girls school), today the term is used exclusively in reference to sexual attraction, activity, and orientation. The term homosocial is now used to describe single-sex contexts that are not specifically sexual. There is also a word referring to same-sex love, homophilia.

Some synonyms for same-sex attraction or sexual activity include men who have sex with men or MSM (used in the medical community when specifically discussing sexual activity) and homoerotic (referring to works of art). Pejorative terms in English include queer, faggot, fairy, poof, and homo. Beginning in the 1990s, some of these have been reclaimed as positive words by gay men and lesbians, as in the usage of queer studies, queer theory, and even the popular American television program Queer Eye for the Straight Guy. The word homo occurs in many other languages without the pejorative connotations it has in English. As with ethnic slurs and racial slurs, however, the misuse of these terms can still be highly offensive; the range of acceptable use depends on the context and speaker. Conversely, gay, a word originally embraced by homosexual men and women as a positive, affirmative term (as in gay liberation and gay rights), has come into widespread pejorative use among young people.

History

Main articles: LGBT history and Timeline of LGBT history

Societal attitudes towards same-sex relationships have varied over time and place, from expecting all males to engage in same-sex relationships, to casual integration, through acceptance, to seeing the practice as a minor sin, repressing it through law enforcement and judicial mechanisms, and to proscribing it under penalty of death.

In a detailed compilation of historical and ethnographic materials of Preindustrial Cultures, "strong disapproval of homosexuality was reported for 41% of 42 cultures; it was accepted or ignored by 21%, and 12% reported no such concept. Of 70 ethnographies, 59% reported homosexuality absent or rare in frequency and 41% reported it present or not uncommon."

In cultures influenced by Abrahamic religions, the law and the church established sodomy as a transgression against divine law or a crime against nature. The condemnation of anal sex between males, however, predates Christian belief. It was frequent in ancient Greece; "unnatural" can be traced back to Plato.

Many historical figures, including Socrates, Lord Byron, Edward II, and Hadrian, have had terms such as gay or bisexual applied to them; some scholars, such as Michel Foucault, have regarded this as risking the anachronistic introduction of a contemporary construction of sexuality foreign to their times, though others challenge this.

Regarding homosexuality nature and historic expression there are two seemingly opposite positions. These are represented by a constructionist and an essentialist approach. In general Social constructionism considers that there are "social constructions" resulting from the many characteristics of a particular social group, and not from some essential nature of the individual self. On the other hand Essentialists defend the existence of real essences that define the individual’s expressions, and social learned aspects are only secondary. David M. Halperin devotes a chapter:Homosexuality: a cultural construct of his work One Hundred Years of Homosexuality to this subject. He says that the essentialism applied to sexual categories means that the terms like "gay" or "straight" refer to culturally not modifiable, essentially personal traits. On the contrary, Constructionists mean that these terms are the names of social processes. Halperin leans towards this last position, as he considers that sexuality, including homosexuality, has been expressed in essentially different ways in different historic societies, as it is in present day ones. He, nevertheless, cites Esteven Epstein that compares the controversy between essentialists and constructionists to the general nature versus nurture debate. As one of the main representatives of essentialists he cites John Boswell, and Michel Foucault as a prominent constructionist.

Gay generally refers to male homosexuality, but may be used in a broader sense to refer to all LGBT people. In the context of sexuality, lesbian refers only to female homosexuality. The word "lesbian" is derived from the name of the Greek island Lesbos, where the poet Sappho wrote largely about her emotional relationships with young women.

Africa

Though often ignored or suppressed by European explorers and colonialists, homosexual expression in native Africa was also present and took a variety of forms. Anthropologists Stephen Murray and Will Roscoe reported that women in Lesotho engaged in socially sanctioned "long term, erotic relationships" called motsoalle. E. E. Evans-Pritchard also recorded that male Azande warriors in the northern Congo routinely took on young male lovers between the ages of twelve and twenty, who helped with household tasks and participated in intercrural sex with their older husbands. The practice had died out by the early 20th century, after Europeans had gained control of African countries, but was recounted to Evans-Pritchard by the elders to whom he spoke.

The first record of possible homosexual couple in history is commonly regarded as Khnumhotep and Niankhkhnum, an Egyptian male couple, who lived around 2400 BCE. The pair are portrayed in a nose-kissing position, the most intimate pose in Egyptian art, surrounded by what appear to be their heirs.

Americas

Among indigenous peoples of the Americas prior to European colonization, a common form of same-sex sexuality centered around the figure of the Two-Spirit individual. Typically this individual was recognized early in life, given a choice by the parents to follow the path and, if the child accepted the role, raised in the appropriate manner, learning the customs of the gender it had chosen. Two-Spirit individuals were commonly shamans and were revered as having powers beyond those of ordinary shamans. Their sexual life was with the ordinary tribe members of the same sex.

Homosexual and transgender individuals were also common among other pre-conquest civilizations in Latin America, such as the Aztecs, Mayans, Quechuas, Moches, Zapotecs, and the Tupinambá of Brazil.

The Spanish conquerors were horrified to discover sodomy openly practiced among native peoples, and attempted to crush it out by subjecting the berdaches (as the Spanish called them) under their rule to severe penalties, including public execution, burning and being torn to pieces by dogs.

East Asia

In East Asia, same-sex love has been referred to since the earliest recorded history.

Homosexuality in China, known as the passions of the cut peach and various other euphemisms has been recorded since approximately 600 BCE. Homosexuality was mentioned in many famous works of Chinese literature. The instances of same-sex affection and sexual interactions described in the classical novel Dream of the Red Chamber seem as familiar to observers in the present as do equivalent stories of romances between heterosexual people during the same period. Confucianism, being primarily a social and political philosophy, focused little on sexuality, whether homosexual or heterosexual. Opposition to homosexuality in China originates in the medieval Tang Dynasty (618-907), attributed to the rising influence of Christian and Islamic values, but did not become fully established until the Westernization efforts of the late Qing Dynasty and the Republic of China.

Homosexuality in Japan, variously known as shudo or nanshoku has been documented for over one thousand years and was an integral part of Buddhist monastic life and the samurai tradition. This same-sex love culture gave rise to strong traditions of painting and literature documenting and celebrating such relationships.

Similarly, in Thailand, Kathoey, or "ladyboys", have been a feature of Thai society for many centuries, and Thai kings had male as well as female lovers. While Kathoey may encompass simple effeminacy or transvestism, it most commonly is treated in Thai culture as a third gender. They are generally accepted by society, and Thailand has never had legal prohibitions against homosexuality or homosexual behavior.

South Asia

The Laws of Manu, the foundational work of Hindu law, mentions a "third sex", members of which may engage in nontraditional gender expression and homosexual activities. The Hijra are a caste of third-gender, or transgender group who live a feminine role. Hijra may be born male or intersex, and some may have been born female.

Throughout Hindu and Vedic texts there are many descriptions of saints, demigods, and even the Supreme Lord transcending gender norms and manifesting multiple combinations of sex and gender. There are several instances in ancient Indian epic poetry of same sex depictions and unions by gods and goddesses. There are several stories of depicting love between same sexes especially among kings and queens. Kama Sutra, the ancient Indian treatise on love talks about feelings for same sexes. Transsexuals are also venerated e.g. Lord Vishnu as Mohini and Lord Shiva as Ardhanarishvara (which means half woman).

Europe

The earliest Western documents (in the form of literary works, art objects, and mythographic materials) concerning same-sex relationships are derived from ancient Greece.

In regard of male homosexuality such documents depict a world in which relationships with women and relationships with youths were the essential foundation of a normal man's love life. Same-sex relationships were a social institution variously constructed over time and from one city to another. The formal practice, an erotic yet often restrained relationship between a free adult male and a free adolescent, was valued for its pedagogic benefits and as a means of population control, though occasionally blamed for causing disorder. Plato praised its benefits in his early writings but in his late works proposed its prohibition. In the Symposium (182B-D), Plato equates acceptance of homosexuality with democracy, and its suppression with despotism, saying that homosexuality "is shameful to barbarians because of their despotic governments, just as philosophy and athletics are, since it is apparently not in best interests of such rulers to have great ideas engendered in their subjects, or powerful friendships or physical unions, all of which love is particularly apt to produce". Aristotle, in the Politics, dismissed Plato's ideas about abolishing homosexuality (2.4); he explains that barbarians like the Celts accorded it a special honor (2.6.6), while the Cretans used it to regulate the population (2.7.5).

Female youths are depicted surrounding Sappho in this painting of Lafond "Sappho sings for Homer", 1824.

Little is known of female homosexuality in antiquity. Sappho, born on the island of Lesbos, was included by later Greeks in the canonical list of nine lyric poets. The adjectives deriving from her name and place of birth (Sapphic and Lesbian) came to be applied to female homosexuality beginning in the 19th century. Sappho's poetry centers on passion and love for various personages and both genders. The narrators of many of her poems speak of infatuations and love (sometimes requited, sometimes not) for various females, but descriptions of physical acts between women are few and subject to debate.

In Ancient Rome the young male body remained a focus of male sexual attention, but relationships were between older free men and slaves or freed youths who took the receptive role in sex. All the emperors with the exception of Claudius took male lovers. The Hellenophile emperor Hadrian is renowned for his relationship with Antinous, but the Christian emperor Theodosius I decreed a law on August 6, 390, condemning passive males to be burned at the stake. Justinian, towards the end of his reign, expanded the proscription to the active partner as well (in 558), warning that such conduct can lead to the destruction of cities through the "wrath of God". Notwithstanding these regulations, taxes on brothels of boys available for homosexual sex continued to be collected until the end of the reign of Anastasius I in 518.

During the Renaissance, wealthy cities in northern Italy — Florence and Venice in particular — were renowned for their widespread practice of same-sex love, engaged in by a considerable part of the male population and constructed along the classical pattern of Greece and Rome. But even as many of the male population were engaging in same-sex relationships, the authorities, under the aegis of the Officers of the Night court, were prosecuting, fining, and imprisoning a good portion of that population. From the second half of the 13th century, death was the punishment for male homosexuality in most of Europe. The eclipse of this period of relative artistic and erotic freedom was precipitated by the rise to power of the moralizing monk Girolamo Savonarola. In northern Europe the artistic discourse on sodomy was turned against its proponents by artists such as Rembrandt, who in his Rape of Ganymede no longer depicted Ganymede as a willing youth, but as a squalling baby attacked by a rapacious bird of prey.

The relationships of socially prominent figures, such as King James I and the Duke of Buckingham, served to highlight the issue, including in anonymously authored street pamphlets: "The world is chang'd I know not how, For men Kiss Men, not Women now;...Of J. the First and Buckingham: He, true it is, his Wives Embraces fled, To slabber his lov'd Ganimede" (Mundus Foppensis, or The Fop Display'd, 1691).

Love Letters Between a Certain Late Nobleman and the Famous Mr. Wilson was published in 1723 in England and was presumed by some modern scholars to be a novel. The 1749 edition of John Cleland's popular novel Fanny Hill includes a homosexual scene, but this was removed in its 1750 edition. Also in 1749, the earliest extended and serious defense of homosexuality in English, Ancient and Modern Pederasty Investigated and Exemplified, written by Thomas Cannon, was published, but was suppressed almost immediately. It includes the passage, "Unnatural Desire is a Contradiction in Terms; downright Nonsense. Desire is an amatory Impulse of the inmost human Parts." Around 1785 Jeremy Bentham wrote another defense, but this was not published until 1978. Executions for sodomy continued in the Netherlands until 1803, and in England until 1835.

Between 1864 and 1880 Karl Heinrich Ulrichs published a series of twelve tracts, which he collectively titled Research on the Riddle of Man-Manly Love. In 1867, he became the first self-proclaimed homosexual person to speak out publicly in defense of homosexuality when he pleaded at the Congress of German Jurists in Munich for a resolution urging the repeal of anti-homosexual laws. Sexual Inversion by Havelock Ellis, published in 1896, challenged theories that homosexuality was abnormal, as well as stereotypes, and insisted on the ubiquity of homosexuality and its association with intellectual and artistic achievement. Although medical texts like these (written partly in Latin to obscure the sexual details) were not widely read by the general public, they did lead to the rise of Magnus Hirschfeld's Scientific-Humanitarian Committee, which campaigned from 1897 to 1933 against anti-sodomy laws in Germany, as well as a much more informal, unpublicized movement among British intellectuals and writers, led by such figures as Edward Carpenter and John Addington Symonds. Beginning in 1894 with Homogenic Love, Socialist activist and poet Edward Carpenter wrote a string of pro-homosexual articles and pamphlets, and "came out" in 1916 in his book My Days and Dreams. In 1900, Elisar von Kupffer published an anthology of homosexual literature from antiquity to his own time, Lieblingminne und Freundesliebe in der Weltliteratur.

Among some Middle Eastern Muslim cultures, egalitarian or age-structured homosexual practices were widespread and thinly veiled. The prevailing pattern of same-sex relationships in the temperate and sub-tropical zone stretching from Northern India to the Western Sahara is one in which the relationships were—and are—either gender-structured or age-structured or both. In recent years, egalitarian relationships modeled on the western pattern have become more frequent, though they remain rare. Same-sex intercourse officially carries the death penalty in several Muslim nations: Saudi Arabia, Iran, Mauritania, northern Nigeria, Sudan, and Yemen.

Israel is considered the most tolerant country in the Middle East and Asia to homosexuals, while the Israeli city Tel Aviv has been named "the gay capital of the Middle East," and is considered one of the most gay friendly cities in the world. The annual Pride Parade in support of homosexuality takes place in Tel Aviv.

Some scholars argue that there are examples of homosexual love in ancient literature, like in the Mesopotamian Epic of Gilgamesh as well as in the Biblical story of David and Jonathan. In the Epic of Gilgamesh, the relationship between the main protagonist Gilgamesh and the character Enkidu has been seen by some to be homosexual in nature. Similarly, David's love for Jonathan is "greater than the love of women."

There are a handful of accounts by Arab travelers to Europe during the mid-1800s. Two of these travelers, Rifa'ah al-Tahtawi and Muhammad sl-Saffar, show their surprise that the French sometimes deliberately mis-translated love poetry about a young boy, instead referring to a young female, to maintain their social norms and morals.

In Persia homosexuality and homoerotic expressions were tolerated in numerous public places, from monasteries and seminaries to taverns, military camps, bathhouses, and coffee houses. In the early Safavid era (1501–1723), male houses of prostitution (amrad khane) were legally recognized and paid taxes.

Today, governments in the Middle East often ignore, deny the existence of, or criminalize homosexuality. Homosexuality is illegal in almost all Muslim countries. Iranian President Mahmoud Ahmadinejad, during his 2007 speech at Columbia University, asserted that there were no gay people in Iran. However, the probable reason is that they keep their sexuality a secret for fear of government sanction or rejection by their families.

South Pacific

In many societies of Melanesia, especially in Papua New Guinea, same-sex relationships were an integral part of the culture until the middle of the last century. The Etoro and Marind-anim for example, even viewed heterosexuality as sinful and celebrated homosexuality instead. In many traditional Melanesian cultures a prepubertal boy would be paired with an older adolescent who would become his mentor and who would "inseminate" him (orally, anally, or topically, depending on the tribe) over a number of years in order for the younger to also reach puberty. Many Melanesian societies, however, have become hostile towards same-sex relationships since the introduction of Christianity by European missionaries.

Sexuality and identity

Kinsey scale

The Kinsey scale, also called the Heterosexual-Homosexual Rating Scale, attempts to describe a person's sexual history or episodes of his or her sexual activity at a given time. It uses a scale from 0, meaning exclusively heterosexual, to 6, meaning exclusively homosexual. In both the Male and Female volumes of the Kinsey Reports, an additional grade, listed as "X", was used for asexuality.

Orientation and behavior

Main articles: Sexual orientation and Sexual orientation identity

The American Psychological Association, the American Psychiatric Association, and the National Association of Social Workers identify sexual orientation as "not merely a personal characteristic that can be defined in isolation. Rather, one's sexual orientation defines the universe of persons with whom one is likely to find the satisfying and fulfilling relationships":

Sexual orientation is commonly discussed as a characteristic of the individual, like biological sex, gender identity, or age. This perspective is incomplete because sexual orientation is always defined in relational terms and necessarily involves relationships with other individuals. Sexual acts and romantic attractions are categorized as homosexual or heterosexual according to the biological sex of the individuals involved in them, relative to each other. Indeed, it is by acting—or desiring to act—with another person that individuals express their heterosexuality, homosexuality, or bisexuality. This includes actions as simple as holding hands with or kissing another person. Thus, sexual orientation is integrally linked to the intimate personal relationships that human beings form with others to meet their deeply felt needs for love, attachment, and intimacy. In addition to sexual behavior, these bonds encompass nonsexual physical affection between partners, shared goals and values, mutual support, and ongoing commitment.

Coming out of the closet

Main article: Coming out

"Coming out (of the closet)" is a phrase which refers to one's disclosure of their sexual orientation or gender identity, and is described and experienced variously as a psychological process or journey. Generally, coming out is described in three phases. The first phase is the phase of "knowing oneself", and the realization emerges that one is open to same-sex relations. This is often described as an internal coming out. The second phase involves one's decision to come out to others, e.g. family, friends, or colleagues. The third phase more generally involves living openly as an LGBT person. In the United States today, people often come out during high school or college age. At this age, they may not trust or ask for help from others, especially when their orientation is not accepted in society. Sometimes their own families are not even informed.

According to Rosario, Schrimshaw, Hunter, Braun (2006), "the development of a lesbian, gay, or bisexual (LGB) sexual identity is a complex and often difficult process. Unlike members of other minority groups (e.g., ethnic and racial minorities), most LGB individuals are not raised in a community of similar others from whom they learn about their identity and who reinforce and support that identity. Rather, LGB individuals are often raised in communities that are either ignorant of or openly hostile toward homosexuality."

Outing is the practice of publicly revealing the sexual orientation of a closeted person. Notable politicians, celebrities, military service people, and clergy members have been outed, with motives ranging from malice to political or moral beliefs. Many commentators oppose the practice altogether, while some encourage outing public figures who use their positions of influence to harm other gay people.

Gender identity

The earliest writers on a homosexual orientation usually understood it to be intrinsically linked to the subject's own sex. For example, it was thought that a typical female-bodied person who is attracted to female-bodied persons would have masculine attributes, and vice versa. This understanding was shared by most of the significant theorists of homosexuality from the mid-19th century to early 20th century, such as Karl Heinrich Ulrichs, Richard von Krafft-Ebing, Magnus Hirschfeld, Havelock Ellis, Carl Jung and Sigmund Freud, as well as many gender variant homosexual people themselves. However, this understanding of homosexuality as sexual inversion was disputed at the time, and through the second half of the 20th century, gender identity came to be increasingly seen as a phenomenon distinct from sexual orientation.

Transgender and cisgender people may be attracted to men, women or both, although the prevalence of different sexual orientations is quite different in these two populations (see sexual orientation of transwomen). An individual homosexual, heterosexual or bisexual person may be masculine, feminine, or androgynous, and in addition, many members and supporters of lesbian and gay communities now see the "gender-conforming heterosexual" and the "gender-nonconforming homosexual" as negative stereotypes. However, studies by J. Michael Bailey and K.J. Zucker have found that a majority of gay men and lesbians report being gender-nonconforming during their childhood years. Richard C. Friedman, in Male Homosexuality published in 1990, writing from a psychoanalytic perspective, argues that sexual desire begins later than the writings of Sigmund Freud indicate, not in infancy but between the ages of 5 and 10 and is not focused on a parent figure but on peers. As a consequence, he reasons, homosexual men are not abnormal, never having been sexually attracted to their mothers anyway.

Same-sex relationships

Male homosexuality symbol

People with a homosexual orientation can express their sexuality in a variety of ways, and may or may not express it in their behaviors. Many have sexual relationships predominately with people of their own gender identity, though some have sexual relationships with those of the opposite gender, bisexual relationships, or none at all (celibate). The Kinsey scale attempts to describe a person's sexual history or episodes of their sexual activity at a given time. It uses a scale from 0, meaning exclusively heterosexual, to 6, meaning exclusively homosexual. It is based on actual sexual behavior surveys. Research indicates that many lesbians and gay men want, and succeed in having, committed and durable relationships. For example, survey data indicate that between 40% and 60% of gay men and between 45% and 80% of lesbians are currently involved in a romantic relationship. Survey data also indicate that between 18% and 28% of gay couples and between 8% and 21% of lesbian couples in the U.S. have lived together ten or more years. Studies have found same-sex and opposite-sex couples to be equivalent to each other in measures of satisfaction and commitment in relationships, that age and gender are more reliable than sexual orientation as a predictor of satisfaction and commitment to a relationship, and that people who are heterosexual or homosexual share comparable expectations and ideals with regard to romantic relationships.

Demographics

Main article: Demographics of sexual orientation

Reliable data as to the size of the gay and lesbian population are of value in informing public policy. For example, demographics would help in calculating the costs and benefits of domestic partnership benefits, of the impact of legalizing gay adoption, and of the impact of the U.S. military's Don't Ask Don't Tell policy. Further, knowledge of the size of the "gay and lesbian population holds promise for helping social scientists understand a wide array of important questions—questions about the general nature of labor market choices, accumulation of human capital, specialization within households, discrimination, and decisions about geographic location."

Measuring the prevalence of homosexuality presents difficulties. It is necessary to consider the measuring criteria that is used, the cutoff point and the time span taken to define a sexual orientation. Many people, despite having same-sex attractions, may be reluctant to identify themselves as gay or bisexual. The research must measure some characteristic that may or may not be defining of sexual orientation. The number of people with same-sex desires may be larger than the number of people who act on those desires, which in turn may be larger than the number of people who self-identify as gay, lesbian, or bisexual.

In 1948 and 1953, Alfred Kinsey reported that nearly 46% of the male subjects had "reacted" sexually to persons of both sexes in the course of their adult lives, and 37% had had at least one homosexual experience. Kinsey's methodology was criticized. A later study tried to eliminate the sample bias, but still reached similar conclusions. LeVay cites these Kinsey results as an example of the caution needed to interpret demographic studies, as they may give quite differing numbers depending on what criteria are used to conduct them, in spite of using sound scientific methods.

Estimates of the occurrence of same-sex behavior range from 2 to 10 percent of the population. A 1992 study reported that 6.1% of males in Britain have had a homosexual experience, while in France the number was reported at 4.1%. In New Zealand, a 2006 study suggested that 20% of the population anonymously reported some homosexual feelings with few of them identifying as homosexual. Percentage of persons identifying as homosexual was 2–3%. According to a 2008 poll, 13% of Britons have had some form of same-sex sexual contact while only 6% of Britons identify themselves as either homosexual or bisexual. Contrastingly, a survey by the UK Office for National Statistics (ONS) in 2010 found that 1.5% of Britons identified themselves as gay or bisexual, and the ONS suggests that this is in line with other surveys showing the number between 0.3% and 3%.

According to major studies, 2% to 10% of people have had some form of same-sex sexual contact within their lifetime. In a 2006 study, 20% of respondents anonymously reported some homosexual feelings, although only 2-3% identified themselves as homosexual.

In the United States, according to exit polling on 2008 Election Day for the 2008 presidential election, 4% of the national electorate self-identified as gay, lesbian, or bisexual, the same percentage as in 2004. According to the 2000 United States Census there were about 601,209 same-sex unmarried partner households. In the 2012 presidential election, 5% of the national electorate openly identified themselves as lesbian, gay, or bisexual.

Psychology

Main article: Homosexuality and psychology

Psychology was one of the first disciplines to study a homosexual orientation as a discrete phenomenon. The first attempts to classify homosexuality as a disease were made by the fledgling European sexologist movement in the late 19th century. In 1886 noted sexologist Richard von Krafft-Ebing listed homosexuality along with 200 other case studies of deviant sexual practices in his definitive work, Psychopathia Sexualis. Krafft-Ebing proposed that homosexuality was caused by either "congenital [during birth] inversion" or an "acquired inversion". In the last two decades of the 19th century, a different view began to predominate in medical and psychiatric circles, judging such behavior as indicative of a type of person with a defined and relatively stable sexual orientation. In the late 19th century and early 20th century, pathological models of homosexuality were standard.

The American Psychological Association, the American Psychiatric Association, and the National Association of Social Workers state:

In 1952, when the American Psychiatric Association published its first Diagnostic and Statistical Manual of Mental Disorders, homosexuality was included as a disorder. Almost immediately, however, that classification began to be subjected to critical scrutiny in research funded by the National Institute of Mental Health. That study and subsequent research consistently failed to produce any empirical or scientific basis for regarding homosexuality as a disorder or abnormality, rather than a normal and healthy sexual orientation. As results from such research accumulated, professionals in medicine, mental health, and the behavioral and social sciences reached the conclusion that it was inaccurate to classify homosexuality as a mental disorder and that the DSM classification reflected untested assumptions based on once-prevalent social norms and clinical impressions from unrepresentative samples comprising patients seeking therapy and individuals whose conduct brought them into the criminal justice system.

In recognition of the scientific evidence, the American Psychiatric Association removed homosexuality from the DSM in 1973, stating that "homosexuality per se implies no impairment in judgment, stability, reliability, or general social or vocational capabilities." After thoroughly reviewing the scientific data, the American Psychological Association adopted the same position in 1975, and urged all mental health professionals "to take the lead in removing the stigma of mental illness that has long been associated with homosexual orientations." The National Association of Social Workers has adopted a similar policy.

Thus, mental health professionals and researchers have long recognized that being homosexual poses no inherent obstacle to leading a happy, healthy, and productive life, and that the vast majority of gay and lesbian people function well in the full array of social institutions and interpersonal relationships.

The longstanding consensus of research and clinical literature demonstrates that same-sex sexual and romantic attractions, feelings, and behaviors are normal and positive variations of human sexuality. There is now a large body of research evidence that indicates that being gay, lesbian or bisexual is compatible with normal mental health and social adjustment. The World Health Organization's ICD-9 (1977) listed homosexuality as a mental illness; it was removed from the ICD-10, endorsed by the Forty-third World Health Assembly on May 17, 1990. Like the DSM-II, the ICD-10 added ego-dystonic sexual orientation to the list, which refers to people who want to change their gender identities or sexual orientation because of a psychological or behavioral disorder (F66.1). The Chinese Society of Psychiatry removed homosexuality from its Chinese Classification of Mental Disorders in 2001 after five years of study by the association. According to the Royal College of Psychiatrists "This unfortunate history demonstrates how marginalisation of a group of people who have a particular personality feature (in this case homosexuality) can lead to harmful medical practice and a basis for discrimination in society. There is now a large body of research evidence that indicates that being gay, lesbian or bisexual is compatible with normal mental health and social adjustment. However, the experiences of discrimination in society and possible rejection by friends, families and others, such as employers, means that some LGB people experience a greater than expected prevalence of mental health difficulties and substance misuse problems. Although there have been claims by conservative political groups in the USA that this higher prevalence of mental health difficulties is confirmation that homosexuality is itself a mental disorder, there is no evidence whatever to substantiate such a claim."

Most lesbian, gay, and bisexual people who seek psychotherapy do so for the same reasons as heterosexual people (stress, relationship difficulties, difficulty adjusting to social or work situations, etc.); their sexual orientation may be of primary, incidental, or no importance to their issues and treatment. Whatever the issue, there is a high risk for anti-gay bias in psychotherapy with lesbian, gay, and bisexual clients. Psychological research in this area has been relevant to counteracting prejudicial ("homophobic") attitudes and actions, and to the LGBT rights movement generally.

The appropriate application of affirmative psychotherapy is based on the following scientific facts:

• Same-sex sexual attractions, behavior, and orientations per se are normal and positive variants of human sexuality; in other words, they are not indicators of mental or developmental disorders.
• Homosexuality and bisexuality are stigmatized, and this stigma can have a variety of negative consequences (e.g., Minority Stress) throughout the life span (D'Augelli & Patterson, 1995; DiPlacido, 1998; Herek & Garnets, 2007; Meyer, 1995, 2003).
• Same-sex sexual attractions and behavior can occur in the context of a variety of sexual orientations and sexual orientation identities (Diamond, 2006; Hoburg et al., 2004; Rust, 1996; Savin-Williams, 2005).
• Gay men, lesbians, and bisexual individuals can live satisfying lives as well as form stable, committed relationships and families that are equivalent to heterosexual relationships in essential respects (APA, 2005c; Kurdek, 2001, 2003, 2004; Peplau & Fingerhut, 2007).
• There are no empirical studies or peer-reviewed research that support theories attributing same-sex sexual orientation to family dysfunction or trauma (Bell et al., 1981; Bene, 1965; Freund & Blanchard, 1983; Freund & Pinkava, 1961; Hooker, 1969; McCord et al., 1962; D. K. Peters & Cantrell, 1991; Siegelman, 1974, 1981; Townes et al., 1976).

Cause

Main articles: Biology and sexual orientation and Environment and sexual orientation

The causes of homosexuality, and more generically the causes of human sexual orientation, have been the subject of abundant scientific inquiry, and the activity has been developed mainly in the direction of biological and environmental factors. The biological factors that have been researched are genetic and hormonal, particularly during the fetal developmental period, that influence the resulting brain structure, and other characteristics such as handedness. There are a wide range of environmental factors (sociological, psychological, or early uterine environment), and various biological factors, that may influence sexual orientation; though many researchers believe that it is caused by a complex interplay between nature and nurture, they favor biological models for the cause.

The American Academy of Pediatrics stated in Pediatrics in 2004:

Sexual orientation probably is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences. In recent decades, biologically based theories have been favored by experts. Although there continues to be controversy and uncertainty as to the genesis of the variety of human sexual orientations, there is no scientific evidence that abnormal parenting, sexual abuse, or other adverse life events influence sexual orientation. Current knowledge suggests that sexual orientation is usually established during early childhood.

The American Psychological Association, American Psychiatric Association, and National Association of Social Workers stated in 2006:

Currently, there is no scientific consensus about the specific factors that cause an individual to become heterosexual, homosexual, or bisexual—including possible biological, psychological, or social effects of the parents' sexual orientation. However, the available evidence indicates that the vast majority of lesbian and gay adults were raised by heterosexual parents and the vast majority of children raised by lesbian and gay parents eventually grow up to be heterosexual.

The Royal College of Psychiatrists stated in 2007:

Despite almost a century of psychoanalytic and psychological speculation, there is no substantive evidence to support the suggestion that the nature of parenting or early childhood experiences play any role in the formation of a person's fundamental heterosexual or homosexual orientation. It would appear that sexual orientation is biological in nature, determined by a complex interplay of genetic factors and the early uterine environment. Sexual orientation is therefore not a choice.

The American Psychological Association states "there are probably many reasons for a person's sexual orientation and the reasons may be different for different people", and says most people's sexual orientation is determined at an early age. Research into how sexual orientation in males may be determined by genetic or other prenatal factors plays a role in political and social debates about homosexuality, and also raises concerns about genetic profiling and prenatal testing.

Professor Michael King states: "The conclusion reached by scientists who have investigated the origins and stability of sexual orientation is that it is a human characteristic that is formed early in life, and is resistant to change. Scientific evidence on the origins of homosexuality is considered relevant to theological and social debate because it undermines suggestions that sexual orientation is a choice."

Innate bisexuality (or predisposition to bisexuality) is a term introduced by Sigmund Freud, based on work by his associate Wilhelm Fliess, that expounds that all humans are born bisexual but through psychological development—which includes both external and internal factors—become monosexual, while the bisexuality remains in a latent state.

The authors of a 2008 study stated "there is considerable evidence that human sexual orientation is genetically influenced, so it is not known how homosexuality, which tends to lower reproductive success, is maintained in the population at a relatively high frequency". They hypothesized that "while genes predisposing to homosexuality reduce homosexuals' reproductive success, they may confer some advantage in heterosexuals who carry them". Their results suggested that "genes predisposing to homosexuality may confer a mating advantage in heterosexuals, which could help explain the evolution and maintenance of homosexuality in the population". A 2009 study also suggested a significant increase in fecundity in the females related to the homosexual people from the maternal line (but not in those related from the paternal one).

Garcia-Falgueras and Swaab state in the abstract of their 2010 study, "The fetal brain develops during the intrauterine period in the male direction through a direct action of testosterone on the developing nerve cells, or in the female direction through the absence of this hormone surge. In this way, our gender identity (the conviction of belonging to the male or female gender) and sexual orientation are programmed or organized into our brain structures when we are still in the womb. There is no indication that social environment after birth has an effect on gender identity or sexual orientation."

Lesbian narratives and sexual orientation awareness

Lesbians often experience their sexuality differently from gay men, and have different understandings about etiology from those derived from studies focused mostly on men. For information specific to female homosexuality, see Lesbian.

In a U.S.-based 1970s mail survey by Shere Hite, lesbians self-reported their reasons for being lesbian. This is the only major piece of research into female sexuality that has looked at how women understand being homosexual since Kinsey in 1953. The research yielded information about women's general understanding of lesbian relationships and their sexual orientation.

Women talked about social conditioning, which made it "almost impossible for me to have a truly healthy sexual relationship with a man". Another woman stated that because of their conditioning "[w]omen are much more sensitive to other people's needs", and so "[s]ex is better with women physically and emotionally", stating she preferred the symmetries of power and aesthetic between women. Some talked about preferring women, "[p]ersonally, I like girls better, they are more tender and loving", and some went into how they found that emotional relationships with women were more satisfying than those with men, with women making more creative and versatile lovers. One woman reported it was easier for her "to give myself emotionally to a woman". A woman who had been a lesbian for two years said she found that sexual relationships with women were more pleasurable on both psychological and physical levels than with men; this was "because the women I've had sex with have been my friends first, which was never the case with men. Being friends sets up a trust that I think is essential for satisfying physical intimacy. Relating to another woman physically seems to me like the most natural thing in the world. You've already got a head start on knowing how to give her pleasure. Gentleness seems to be the key, and is the main difference between relating to men and women.'" Women talked about women making better sexual partners and that was a dominant theme: "I find women better lovers; they know what a woman wants and most of all there is an emotional closeness that can never be matched with a man. More tenderness, more consideration and understanding of feelings, etc." This was because men were perceived as unliberated "sexually or emotionally or any other way", and lesbianism was perceived "as an alternative to abstinence" and to men generally. Men were perceived as usually juvenile, while a relationship with women was described as "more of a communion with self". Sex as well as relationships with women were seen as a way of achieving independence from men; "[s]ex with a woman means independence from men." Male sexual performance was another problem, "[t]wenty minutes for a man, at least an hour with a woman, usually more", as well as attention to the sexual needs of women who themselves "seem to have a more sustained energy level after orgasm, and are more likely to know and do something about it if I'm not satisfied". One understanding of the difference was that sex with women "is not an 'exchange' or a 'trade' or services", and not focused on orgasm, with "more kissing and holding" and "more concern for my pleasure", which was experienced as liberating. Sex with women was also seen as a political act; "I see lesbianism as putting all my energies (sexual, political social, etc.) into women. Sex is a form of comfort and to have sex indiscriminately with males is to give them comfort.".

Hite is more concerned with what respondents say than quantifiable data. She found the two most significant differences between respondents' experience with men and women were the focus on clitoral stimulation, and more emotional involvement and orgasmic responses. Since Hite carried out her study she has acknowledged that some women may have chosen the political identity of a lesbian. Julie Bindel, a UK journalist, reaffirmed that "political lesbianism continues to make intrinsic sense because it reinforces the idea that sexuality is a choice, and we are not destined to a particular fate because of our chromosomes." as recently as 2009.

Sexual orientation change efforts

Main article: Sexual orientation change efforts

There are no studies of adequate scientific rigor to conclude whether recent sexual orientation change efforts do work to change a person's sexual orientation. Those efforts have been controversial due to tensions between the values held by some faith-based organizations, on the one hand, and those held by LGBT rights organizations and professional and scientific organizations and other faith-based organizations, on the other. The longstanding consensus of the behavioral and social sciences and the health and mental health professions is that homosexuality per se is a normal and positive variation of human sexual orientation, and therefore not a mental disorder. The American Psychological Association says that "most people experience little or no sense of choice about their sexual orientation". Some individuals and groups have promoted the idea of homosexuality as symptomatic of developmental defects or spiritual and moral failings and have argued that sexual orientation change efforts, including psychotherapy and religious efforts, could alter homosexual feelings and behaviors. Many of these individuals and groups appeared to be embedded within the larger context of conservative religious political movements that have supported the stigmatization of homosexuality on political or religious grounds.

No major mental health professional organization has sanctioned efforts to change sexual orientation and virtually all of them have adopted policy statements cautioning the profession and the public about treatments that purport to change sexual orientation. These include the American Psychiatric Association, American Psychological Association, American Counseling Association, National Association of Social Workers in the USA, the Royal College of Psychiatrists, and the Australian Psychological Society. The American Psychological Association and the Royal College of Psychiatrists expressed concerns that the positions espoused by NARTH are not supported by the science and create an environment in which prejudice and discrimination can flourish.

The American Psychological Association "encourages mental health professionals to avoid misrepresenting the efficacy of sexual orientation change efforts by promoting or promising change in sexual orientation when providing assistance to individuals distressed by their own or others' sexual orientation and concludes that the benefits reported by participants in sexual orientation change efforts can be gained through approaches that do not attempt to change sexual orientation".

Fluidity of orientation

The American Psychiatric Association (APA) has stated "some people believe that sexual orientation is innate and fixed; however, sexual orientation develops across a person's lifetime". In a joint statement with other major American medical organizations, the APA says that "different people realize at different points in their lives that they are heterosexual, gay, lesbian, or bisexual". A report from the Centre for Addiction and Mental Health states: "For some people, sexual orientation is continuous and fixed throughout their lives. For others, sexual orientation may be fluid and change over time". One study has suggested "considerable fluidity in bisexual, unlabeled, and lesbian women's attractions, behaviors, and identities".

Gender and fluidity

In a 2004 study, the female subjects (both gay and straight women) became sexually aroused when they viewed heterosexual as well as lesbian erotic films. Among the male subjects, however, the straight men were turned on only by erotic films with women, the gay ones by those with men. The study's senior researcher said that women's sexual desire is less rigidly directed toward a particular sex, as compared with men's, and it's more changeable over time.

Parenting

See also: LGBT parenting

Scientific research has been generally consistent in showing that lesbian and gay parents are as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as children reared by heterosexual parents. According to scientific literature reviews, there is no evidence to the contrary.

Physical

The terms "Men who have sex with men" (MSM) and "women who have sex with women" (WSW) refer to people who engage in sexual activity with others of the same sex regardless of how they identify themselves—as many choose not to accept social identities as lesbian, gay and bisexual. These terms are often used in medical literature and social research to describe such groups for study, without needing to consider the issues of sexual self-identity. The terms are seen as problematic, however, because they "obscure social dimensions of sexuality; undermine the self-labeling of lesbian, gay, and bisexual people; and do not sufficiently describe variations in sexual behavior". MSM and WSW are sexually active with each other for a variety of reasons with the main ones arguably sexual pleasure, intimacy and bonding. In contrast to its benefits, sexual behavior can be a disease vector. Safe sex is a relevant harm reduction philosophy. The United States currently prohibits men who have sex with men from donating blood "because they are, as a group, at increased risk for HIV, hepatitis B and certain other infections that can be transmitted by transfusion." The UK and many European countries have the same prohibition.

Public health

These safer sex recommendations are agreed upon by public health officials for women who have sex with women to avoid sexually transmitted infections (STIs):

• Avoid contact with a partner’s menstrual blood and with any visible genital lesions.
• Cover sex toys that penetrate more than one person's vagina or anus with a new condom for each person; consider using different toys for each person.
• Use a barrier (e.g., latex sheet, dental dam, cut-open condom, plastic wrap) during oral sex.
• Use latex or vinyl gloves and lubricant for any manual sex that might cause bleeding.

These safer sex recommendations are agreed upon by public health officials for men who have sex with men to avoid sexually transmitted infections:

• Avoid contact with a partner's bodily fluids and with any visible genital lesions.
• Use condoms for anal and oral sex.
• Use a barrier (e.g., latex sheet, dental dam, cut-open condom) during anal–oral sex.
• Cover sex toys that penetrate more than one person with a new condom for each person; consider using different toys for each person and use latex or vinyl gloves and lubricant for any sex that might cause bleeding.

Mental

When it was first described in medical literature, homosexuality was often approached from a view that sought to find an inherent psychopathology as its root cause. Much literature on mental health and homosexual patients centered on their depression, substance abuse, and suicide. Although these issues exist among people who are non-heterosexual, discussion about their causes shifted after homosexuality was removed from the Diagnostic and Statistical Manual (DSM) in 1973. Instead, social ostracism, legal discrimination, internalization of negative stereotypes, and limited support structures indicate factors homosexual people face in Western societies that often adversely affect their mental health. Stigma, prejudice, and discrimination stemming from negative societal attitudes toward homosexuality lead to a higher prevalence of mental health disorders among lesbians, gay men, and bisexuals compared to their heterosexual peers. Evidence indicates that the liberalization of these attitudes over the past few decades is associated with a decrease in such mental health risks among younger LGBT people.

Gay and lesbian youth

Gay and lesbian youth bear an increased risk of suicide, substance abuse, school problems, and isolation because of a "hostile and condemning environment, verbal and physical abuse, rejection and isolation from family and peers". Further, LGBT youths are more likely to report psychological and physical abuse by parents or caretakers, and more sexual abuse. Suggested reasons for this disparity are that (1) LGBT youths may be specifically targeted on the basis of their perceived sexual orientation or gender non-conforming appearance, and (2) that "risk factors associated with sexual minority status, including discrimination, invisibility, and rejection by family members...may lead to an increase in behaviors that are associated with risk for victimization, such as substance abuse, sex with multiple partners, or running away from home as a teenager." A 2008 study showed a correlation between the degree of rejecting behavior by parents of LGB adolescents and negative health problems in the teenagers studied:

Higher rates of family rejection were significantly associated with poorer health outcomes. On the basis of odds ratios, lesbian, gay, and bisexual young adults who reported higher levels of family rejection during adolescence were 8.4 times more likely to report having attempted suicide, 5.9 times more likely to report high levels of depression, 3.4 times more likely to use illegal drugs, and 3.4 times more likely to report having engaged in unprotected sexual intercourse compared with peers from families that reported no or low levels of family rejection.

Crisis centers in larger cities and information sites on the Internet have arisen to help youth and adults. The Trevor Helpline, a suicide prevention helpline for gay youth, was established following the 1998 airing on HBO of the Academy Award winning short film Trevor.

Some jurisdictions further recognize identical rights, protections, and privileges for the family structures of same-sex couples, including marriage. Some nations mandate that all individuals restrict themselves to heterosexual relationships; that is, in some jurisdictions homosexual activity is illegal. Offenders can face the death penalty in some fundamentalist Muslim areas such as Iran and parts of Nigeria. There are, however, often significant differences between official policy and real-world enforcement. See Violence against LGBT people.

Although homosexual acts were decriminalized in some parts of the Western world, such as Poland in 1932, Denmark in 1933, Sweden in 1944, and the United Kingdom in 1967, it was not until the mid-1970s that the gay community first began to achieve limited civil rights in some developed countries. On July 2, 2009, homosexuality was decriminalized in India by a High Court ruling. A turning point was reached in 1973 when the American Psychiatric Association removed homosexuality from the Diagnostic and Statistical Manual of Mental Disorders, thus negating its previous definition of homosexuality as a clinical mental disorder. In 1977, Quebec became the first state-level jurisdiction in the world to prohibit discrimination on the grounds of sexual orientation. During the 1980s and 1990s, most developed countries enacted laws decriminalizing homosexual behavior and prohibiting discrimination against lesbian and gay people in employment, housing, and services. On the other hand, many countries today in the Middle East and Africa, as well as several countries in Asia, the Caribbean and the South Pacific, outlaw homosexuality. In six countries, homosexual behavior is punishable by life imprisonment; in ten others, it carries the death penalty.

Laws against sexual orientation discrimination

United States

• Employment discrimination refers to discriminatory employment practices such as bias in hiring, promotion, job assignment, termination, and compensation, and various types of harassment. In the United States there is "very little statutory, common law, and case law establishing employment discrimination based upon sexual orientation as a legal wrong." Some exceptions and alternative legal strategies are available. President Bill Clinton's Executive Order 13087 (1998) prohibits discrimination based on sexual orientation in the competitive service of the federal civilian workforce, and federal non-civil service employees may have recourse under the Due Process Clause of the U.S. Constitution. Private sector workers may have a Title VII action under a quid pro quo sexual harassment theory, a "hostile work environment" theory, a sexual stereotyping theory, or others.
• Housing discrimination refers to discrimination against potential or current tenants by landlords. In the United States, there is no federal law against such discrimination on the basis of sexual orientation or gender identity, but at least thirteen states and many major cities have enacted laws prohibiting it.
• Hate crimes (also known as bias crimes) are crimes motivated by bias against an identifiable social group, usually groups defined by race (human classification), religion, sexual orientation, disability, ethnicity, nationality, age, gender, gender identity, or political affiliation. In the United States, 45 states and the District of Columbia have statutes criminalizing various types of bias-motivated violence or intimidation (the exceptions are AZ, GA, IN, SC, and WY). Each of these statutes covers bias on the basis of race, religion, and ethnicity; 32 of them cover sexual orientation, 28 cover gender, and 11 cover transgender/gender-identity. In October 2009, the Matthew Shepard and James Byrd, Jr. Hate Crimes Prevention Act, which "...gives the Justice Department the power to investigate and prosecute bias-motivated violence where the perpetrator has selected the victim because of the person's actual or perceived race, color, religion, national origin, gender, sexual orientation, gender identity or disability", was signed into law and makes hate crime based on sexual orientation, amongst other offenses, a federal crime in the United States.

European Union

In the European Union, discrimination of any type based on sexual orientation or gender identity is illegal under the Charter of Fundamental Rights of the European Union.

Since the 1960s, many LGBT people in the West, particularly those in major metropolitan areas, have developed a so-called gay culture. To many, gay culture is exemplified by the gay pride movement, with annual parades and displays of rainbow flags. Yet not all LGBT people choose to participate in "queer culture", and many gay men and women specifically decline to do so. To some it seems to be a frivolous display, perpetuating gay stereotypes. To some others, the gay culture represents heterophobia and is scorned as widening the gulf between gay and non-gay people.

With the outbreak of AIDS in the early 1980s, many LGBT groups and individuals organized campaigns to promote efforts in AIDS education, prevention, research, patient support, and community outreach, as well as to demand government support for these programs.

The bewildering death toll wrought by the AIDS epidemic at first seemed to slow the progress of the gay rights movement, but in time it galvanized some parts of the LGBT community into community service and political action, and challenged the heterosexual community to respond compassionately. Major American motion pictures from this period that dramatized the response of individuals and communities to the AIDS crisis include An Early Frost (1985), Longtime Companion (1990), And the Band Played On (1993), Philadelphia (1993), and Common Threads: Stories from the Quilt (1989).

Publicly gay politicians have attained numerous government posts, even in countries that had sodomy laws in their recent past. Examples include Guido Westerwelle, Germany's Vice-Chancellor; Peter Mandelson, a British Labour Party cabinet minister and Per-Kristian Foss, formerly Norwegian Minister of Finance.

LGBT movements are opposed by a variety of individuals and organizations. Some social conservatives believe that all sexual relationships with people other than an opposite-sex spouse undermine the traditional family and that children should be reared in homes with both a father and a mother. There is concern that gay rights may conflict with individuals' freedom of speech, religious freedoms in the workplace, the ability to run churches, charitable organizations and other religious organizations in accordance with one's religious views, and that the acceptance of homosexual relationships by religious organizations might be forced through threatening to remove the tax-exempt status of churches whose views do not align with those of the government.

Critics charge that political correctness has led to the association of sex between males and HIV being downplayed.

Military service

The US Army defines homosexual conduct as "a homosexual act, a statement by a soldier that demonstrates a propensity or intent to engage in homosexual acts, the solicitation of another to engage in homosexual act or acts, or a homosexual marriage or attempted marriage."

Main article: Sexual orientation and military service

Policies and attitudes toward gay and lesbian military personnel vary widely around the world. Some countries allow gay men, lesbians, and bisexual people to serve openly and have granted them the same rights and privileges as their heterosexual counterparts. Many countries neither ban nor support LGB service members. A few countries continue to ban homosexual personnel outright.

Most Western military forces have removed policies excluding sexual minority members. Of the 26 countries that participate militarily in NATO, more than 20 permit openly gay, lesbian and bisexual people to serve. Of the permanent members of the United Nations Security Council, three (United Kingdom, France and United States) do so. The other two generally do not: China bans gay and lesbian people outright, Russia excludes all gay and lesbian people during peacetime but allows some gay men to serve in wartime (see below). Israel is the only country in the Middle East region that allows openly LGB people to serve in the military.

While the question of homosexuality in the military has been highly politicized in the United States, it is not necessarily so in many countries. Generally speaking, sexuality in these cultures is considered a more personal aspect of one's identity than it is in the United States.

According to American Psychological Association empirical evidence fails to show that sexual orientation is germane to any aspect of military effectiveness including unit cohesion, morale, recruitment and retention. Sexual orientation is irrelevant to task cohesion, the only type of cohesion that critically predicts the team's military readiness and success.

On March 18, 2010, after U.S. President Obama announced that he wanted to put an end to the Don't Ask, Don't Tell policy, former U.S. general and high ranking NATO official John Sheehan blamed homosexuals serving in the Dutch military for the fall of Srebrenica to Serb militias in the Bosnian War fifteen years earlier, stating that homosexuals had weakened the Dutch UN battalion charged with protecting the enclave. In the U.S. Senate, Sheehan said that European countries had tried to "socialize" their armed forces by letting people serve in the army too easily, which according to him, left them weakened. He claimed that his opinion was shared by the leadership of the Dutch armed forces, mentioning the name "Hankman Berman", most probably referring to the then chief of the Dutch defence staff, Henk van den Breemen. Dutch authorities dismissed Sheehan's statements as "disgraceful" and "total nonsense".

Societal acceptance of non-heterosexual orientations such as homosexuality is lowest in Asian and African countries, and is highest in Europe, Australia, and the Americas. Western society has become increasingly accepting of homosexuality over the past few decades.

Relationships

In 2006, the American Psychological Association, American Psychiatric Association and National Association of Social Workers stated in an amicus brief presented to the Supreme Court of the State of California: "Gay men and lesbians form stable, committed relationships that are equivalent to heterosexual relationships in essential respects. The institution of marriage offers social, psychological, and health benefits that are denied to same-sex couples. By denying same-sex couples the right to marry, the state reinforces and perpetuates the stigma historically associated with homosexuality. Homosexuality remains stigmatized, and this stigma has negative consequences. California's prohibition on marriage for same-sex couples reflects and reinforces this stigma". They concluded: "There is no scientific basis for distinguishing between same-sex couples and heterosexual couples with respect to the legal rights, obligations, benefits, and burdens conferred by civil marriage."

Religion

Main article: Religion and homosexuality

Though the relationship between homosexuality and religion can vary greatly across time and place, within and between different religions and sects, and regarding different forms of homosexuality and bisexuality, current authoritative bodies and doctrines of the world's largest religions generally view homosexuality negatively. This can range from quietly discouraging homosexual activity, to explicitly forbidding same-sex sexual practices among adherents and actively opposing social acceptance of homosexuality. Some teach that homosexual orientation itself is sinful, others state that only the sexual act is a sin, others are completely accepting of gays and lesbians, while some encourage homosexuality. Some claim that homosexuality can be overcome through religious faith and practice. On the other hand, voices exist within many of these religions that view homosexuality more positively, and liberal religious denominations may bless same-sex marriages. Some view same-sex love and sexuality as sacred, and a mythology of same-sex love can be found around the world. Regardless of their position on homosexuality, many people of faith look to both sacred texts and tradition for guidance on this issue.

Discrimination

Gay bullying

Main article: Gay bullying

Gay bullying can be the verbal or physical abuse against a person who is perceived by the aggressor to be lesbian, gay, bisexual or transgender, including persons who are actually heterosexual or of non-specific or unknown sexual orientation. In the US, teenage students heard anti-gay slurs such as “homo”, “faggot” and “sissy” about 26 times a day on average, or once every 14 minutes, according to a 1998 study by Mental Health America (formerly National Mental Health Association).

Heterosexism and homophobia

Further information: Heterosexism and Homophobia

Protests in New York City against Uganda's Anti-Homosexuality Bill.

In many cultures, homosexual people are frequently subject to prejudice and discrimination. A 2011 Dutch study concluded that 49% of Holland's youth and 58% of youth foreign to the country reject homosexuality. Similar to other minority groups they can also be subject to stereotyping. These attitudes tend to be due to forms of homophobia and heterosexism (negative attitudes, bias, and discrimination in favor of opposite-sex sexuality and relationships). Heterosexism can include the presumption that everyone is heterosexual or that opposite-sex attractions and relationships are the norm and therefore superior. Homophobia is a fear of, aversion to, or discrimination against homosexual people. It manifests in different forms, and a number of different types have been postulated, among which are internalized homophobia, social homophobia, emotional homophobia, rationalized homophobia, and others. Similar is lesbophobia (specifically targeting lesbians) and biphobia (against bisexual people). When such attitudes manifest as crimes they are often called hate crimes and gay bashing.

Negative stereotypes characterize LGB people as less romantically stable, more promiscuous and more likely to abuse children, but there is no scientific basis to such assertions. Gay men and lesbians form stable, committed relationships that are equivalent to heterosexual relationships in essential respects. Sexual orientation does not affect the likelihood that people will abuse children. Claims that there is scientific evidence to support an association between being gay and being a pedophile are based on misuses of those terms and misrepresentation of the actual evidence.

Violence against gays and lesbians

Main article: Violence against LGBT people

In the United States, the FBI reported that 15.6% of hate crimes reported to police in 2004 were based on perceived sexual orientation. Sixty-one percent of these attacks were against gay men. The 1998 murder of Matthew Shepard, a gay student, is a notorious such incident in the U.S.

Homosexual behavior in non-human animals

Main article: Homosexual behavior in animals

Roy and Silo, two New York Central Park Zoo male Chinstrap Penguins similar to those pictured, became internationally known when they coupled and later were given an egg that needed hatching and care, which they successfully did.

Homosexual behavior in animals refers to the documented evidence of homosexual, bisexual and transgender behavior in non-human animals. Such behaviors include sex, courtship, affection, pair bonding, and parenting. Homosexual and bisexual behavior are widespread in the animal kingdom: a 1999 review by researcher Bruce Bagemihl shows that homosexual behavior has been observed in close to 1500 species, ranging from primates to gut worms, and is well documented for 500 of them. Animal sexual behaviour takes many different forms, even within the same species. The motivations for and implications of these behaviors have yet to be fully understood, since most species have yet to be fully studied. According to Bagemihl, "the animal kingdom [does] it with much greater sexual diversity—including homosexual, bisexual and nonreproductive sex—than the scientific community and society at large have previously been willing to accept."
