Transgender people of all kinds, including transsexual people, can be gay, lesbian, bisexual, or asexual. Sexual orientation is not linked to gender identity. A transsexual person who undergoes gender reassignment surgery may be perceived as having an orientation change if they go from being interested in the "same" gender to the "opposite" gender or vice versa because of their own transition.

Transgender is an umbrella term for people whose gender identity and/or gender expression differs from the sex they were assigned at birth (Gay and Lesbian Alliance Against Defamation [GLAAD], 2007).
In March 2015, the Swiss Federal Council released a governmental report about marriage and new rights for families. It opens the possibility to introduce registered partnerships for different-sex couples as well as same-sex marriage for same-sex couples.[462] Federal Councillor Simonetta Sommaruga in charge of the Federal Department of Justice and Police also stated she hoped personally that same-sex couples would soon be allowed to marry.[463]

There is no consensus among scientists about the exact reasons that an individual develops a heterosexual, bisexual or homosexual orientation.[35] Proposed reasons include a combination of genetic factors[36][37] and environmental factors (including fraternal birth order, where the number of older brothers a boy has increases the chances of homosexuality; specific prenatal hormone exposure, where hormones play a role in determining sexual orientation as they do with sex differentiation;[38][39] and prenatal stress on the mother).[40][41][42]
The Rainbow Flag as we know it today was developed by San Francisco artist Gilbert Baker in 1978. At the time, there was a need for a gay symbol which could be used year after year for the San Francisco Gay and Lesbian Pride Parade. Baker took inspiration from many sources, from the hippies movement to the black civil rights movement, and came up with a flag with eight stripes. Color has always played an important power in the gay right movement- Victorian England symbolized homosexuality with the color green, lavender became popular in the 1960s, and and pink from the pink triangle has caught on as well- and the colors of the gay flag were no different. Baker explained that his colors each stood for a different aspect of gay and lesbian life:

1960年代性革命之前,社会上并没有专门指代非异性恋的中立词汇。最接近中立的词汇是1860年代出现的“第三性”,但这个词并没有在社会上得到广泛接受[12][13][14][15][16][17]。第一个广泛传播的词汇是“同性恋”,但是这个词在1950和1960年代被认为有贬义,所以一度被“同性爱”代替[18],1970年代被“gay”代替[12] 。随着女同性恋受到越来越多的关注,“gay”和“lesbian”的使用变得普遍[1]。女同性恋组织比利提斯的女儿在1970年代提出了女同性恋社群应该更注重哪个方向的争议——应该更关注于女权运动还是同性恋权益[19]。身兼女同性恋身份的女权主义者认为男女平等应优先考量,认为性别分工和男女气质被这个群体认为是父权的象征,不参与当时在酒吧流行的性别角色游戏,也回避男同性恋沙文主义;一些女同性恋的女权主义者不愿意和男同性恋者一起工作[20]。持本质主义观点的女同性恋认为自己生来即为同性恋,倾向于用“lesbian”这个词来形容自己的性倾向,并认为同性恋分离主义和女权主义者的愤怒观点不利于争取同性恋权益。这种态度迅速被双性恋和跨性别人士认可,并一起寻求更大社群的认同[1]。在石墙暴动后的一段时间,即1970和1980年代,男同性恋和女同性恋皆对双性恋和跨性别人士的接纳程度有所降低[21][22]。双性恋被认为是不敢出柜或不能自我认同的同性恋,而跨性别被认为其行为偏离了人们对性别的刻板印象[21]。每个社群都发展出了各自的自我认同,其中包括是否接受其他性别的族群以及如何与其他性别相处的问题,然而这些争论持续至今[22]。


Harry Benjamin invented a classification system for transsexuals and transvestites, called the Sex Orientation Scale (SOS), in which he assigned transsexuals and transvestites to one of six categories based on their reasons for cross-dressing and the relative urgency of their need (if any) for sex reassignment surgery.[50] Benjamin considered a moderate intensity "true transsexual" to need either estrogen or testosterone as a "substitute for or preliminary to operation";[50] people who meet Benjamin's definition of a "true transsexual" but do not desire SRS include Miriam Rivera. There are also people who have had SRS but do not meet the definition of "transsexual", such as Gregory Hemingway.[51][52]


Human bisexuality has mainly been studied alongside homosexuality. Van Wyk and Geist argue that this is a problem for sexuality research because the few studies that have observed bisexuals separately have found that bisexuals are often different from both heterosexuals and homosexuals. Furthermore, bisexuality does not always represent a halfway point between the dichotomy. Research indicates that bisexuality is influenced by biological, cognitive and cultural variables in interaction, and this leads to different types of bisexuality.[34]

Trinidad and Tobago organised its first pride parade on 27 July 2018 at the Nelson Mandela Park in Port of Spain.[172] Expressing his opinion on the march, Roman Catholic Archbishop Rev. Jason Gordon said: "TT is a democracy and as such members of society have a right to protest whenever they believe their rights are not being upheld or violated. (The) LGBT+ community has several areas where there is legitimate concern and these have to be taken seriously by the country and by the government and people of TT.[173] "


...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.[8]
In some cases, animals will choose to engage in sexual activity with different sexes at different times in their lives, and will sometimes engage in sexual activity with different sexes at random. Same-sex sexual activity can also be seasonal in some animals, like male walruses who often engage in same-sex sexual activity with each other outside of the breeding season and will revert to heterosexual sexual activity during breeding season.[137]
From this perspective, the devaluation of same-sex intimacy is immoral because it constitutes arbitrary and irrational discrimination, thereby damaging the community. Most same-sex marriage advocates further held that international human rights legislation provided a universal franchise to equal treatment under the law. Thus, prohibiting a specific group from the full rights of marriage was illegally discriminatory. For advocates of the community-benefit perspective, all the legal perquisites associated with heterosexual marriage should be available to any committed couple.

Jurisdiction over legal classification of sex in Canada is assigned to the provinces and territories. This includes legal change of gender classification. On June 19, 2017 Bill C-16, after having passed the legislative process in the House of Commons of Canada and the Senate of Canada, became law upon receiving Royal Assent which put it into immediate force.[104][105][106] The law updated the Canadian Human Rights Act and the Criminal Code to include "gender identity and gender expression" as protected grounds from discrimination, hate publications and advocating genocide. The bill also added "gender identity and expression" to the list of aggravating factors in sentencing, where the accused commits a criminal offence against an individual because of those personal characteristics. Similar transgender laws also exist in all the provinces and territories.[citation needed]
All states that allow same-sex marriage also allow the joint adoption of children by people of the same sex, with the exceptions of Jalisco, Nayarit and Quintana Roo in Mexico. In addition, Andorra and Israel as well as several subnational jurisdictions which do not recognize same-sex marriage nonetheless permit joint adoption by unmarried same-sex couples: Querétaro and Veracruz in Mexico as well as Northern Ireland and Jersey in the United Kingdom. Some additional states allow stepchild adoption by those who are in a same-sex relationship but are unmarried: Croatia, Estonia, Italy (on a case-by-case basis), Slovenia and Switzerland.[514]

Using a content analysis of more than 170 articles written between 2001 and 2006, sociologist Richard N. Pitt, Jr. concluded that the media pathologized black bisexual men's behavior while either ignoring or sympathizing with white bisexual men's similar actions. He argued that the black bisexual man is often described as a duplicitous heterosexual man spreading the HIV/AIDS virus. Alternatively, the white bisexual man is often described in pitying language as a victimized homosexual man forced into the closet by the heterosexist society around him.[103]
Additionally, fifteen countries which have legalized same-sex marriage still have an alternative form of legal recognition for same-sex couples, usually available to heterosexual couples as well: Argentina, Australia, Austria, Belgium, Brazil, Colombia, France, Luxembourg, Malta, the Netherlands, Portugal, South Africa, Spain, the United Kingdom and Uruguay.[491][492][493][494]

Feminist positions on bisexuality range greatly, from acceptance of bisexuality as a feminist issue to rejection of bisexuality as reactionary and anti-feminist backlash to lesbian feminism.[91] A number of women who were at one time involved in lesbian-feminist activism have since come out as bisexual after realizing their attractions to men. A widely studied example of lesbian-bisexual conflict in feminism was the Northampton Pride March during the years between 1989 and 1993, where many feminists involved debated over whether bisexuals should be included and whether or not bisexuality was compatible with feminism.


The first Italian event specifically associated with international celebrations of Gay Pride was the sixth congress of Fuori! held in Turin in late June 1978 and included a week of films on gay subjects.[77]:103 Episodes of violence against homosexuals were frequent in Italy, such as in the summer of 1979 when two young gay men were killed in Livorno. In Pisa in November of that year, the Orfeo Collective [it] organized the first march against anti-gay violence. Around 500 gay and lesbian participants attended, and this remained the largest gathering of the kind until 1994.[77]:122–124

In Latin American cultures, a travesti is a person who has been assigned male at birth and who has a feminine, transfeminine, or "femme" gender identity. Travestis generally undergo hormonal treatment, use female gender expression including new names and pronouns from the masculine ones they were given when assigned a sex, and might use breast implants, but they are not offered or do not desire sex-reassignment surgery. Travesti might be regarded as a gender in itself (a "third gender"), a mix between man and woman ("intergender/androgynes"), or the presence of both masculine and feminine identities in a single person ("bigender"). They are framed as something entirely separate from transgender women, who possess the same gender identity of people assigned female at birth.[citation needed]

The American Institute of Bisexuality stated that Bailey's study was misinterpreted and misreported by both The New York Times and its critics.[77] In 2011, Bailey and other researchers reported that among men with a history of several romantic and sexual relationships with members of both sexes, high levels of sexual arousal were found in response to both male and female sexual imagery.[78][79] The subjects were recruited from a Craigslist group for men seeking intimacy with both members of a heterosexual couple. The authors said that this change in recruitment strategy was an important difference, but it may not have been a representative sample of bisexual-identified men. They concluded that "bisexual-identified men with bisexual arousal patterns do indeed exist", but could not establish whether such a pattern is typical of bisexual-identified men in general.[79][80]
Baehr v. Lewin, 852 P.2d 44 (Haw. 1993). A statute limiting marriage to opposite-sex couples violates the Hawaii constitution's equal-protection clause unless the state can show that the statute is both justified by compelling state interests and also narrowly tailored. This ruling prompted the adoption of Hawaii's constitutional amendment allowing the Legislature to restrict marriage to different-sex couples and the federal Defense of Marriage Act.
The rainbow flag was deeply established as the symbol for gay pride in 1994 when Baker has created a mile-long variant of the flag on the occasion of Stone riots’ 25th anniversary. Now, it is seen as the global emblem for gay pride during both difficult and promising times all across the globe. The rainbow flag is the true fit for the mission and it proclaims the saying “This is who I’m”.
The classification of a person as male or female. At birth, infants are assigned a sex, usually based on the appearance of their external anatomy. (This is what is written on the birth certificate.) A person's sex, however, is actually a combination of bodily characteristics including: chromosomes, hormones, internal and external reproductive organs, and secondary sex characteristics.
Magnus Hirschfeld argued that adult sexual orientation can be explained in terms of the bisexual nature of the developing fetus: he believed that in every embryo there is one rudimentary neutral center for attraction to males and another for attraction to females. In most fetuses, the center for attraction to the opposite sex developed while the center for attraction to the same sex regressed, but in fetuses that became homosexual, the reverse occurred. Simon LeVay has criticized Hirschfeld's theory of an early bisexual stage of development, calling it confusing; LeVay maintains that Hirschfeld failed to distinguish between saying that the brain is sexually undifferentiated at an early stage of development and saying that an individual actually experiences sexual attraction to both men and women. According to LeVay, Hirschfeld believed that in most bisexual people the strength of attraction to the same sex was relatively low, and that it was therefore possible to restrain its development in young people, something Hirschfeld supported.[47]

On June 29, 2008, four Indian cities (Delhi, Bangalore, Pondicherry and Kolkata) saw coordinated pride events. About 2,200 people turned up overall. These were also the first pride events of all these cities except Kolkata, which had seen its first such event in 1999 - making it South Asia's first pride walk and then had been organizing pride events every year since 2003[49] (although there was a gap of a year or so in-between). The pride parades were successful, given that no right-wing group attacked or protested against the pride parade, although the opposition party BJP expressed its disagreement with the concept of gay pride parade. The next day, Prime Minister Manmohan Singh appealed for greater social tolerance towards homosexuals at an AIDS event. On August 16, 2008 (one day after the Independence Day of India), the gay community in Mumbai held its first ever formal pride parade (although informal pride parades had been held many times earlier), to demand that India's anti-gay laws be amended.[50] A high court in the Indian capital, Delhi ruled on July 2, 2009, that homosexual intercourse between consenting adults was not a criminal act,[51] although the Supreme Court later reversed its decision in 2013 under widespread pressure from powerful conservative and religious groups, leading to the re-criminalization of homosexuality in India.[52] Pride parades have also been held in smaller Indian cities such as Nagpur, Madurai, Bhubaneshwar and Thrissur. Attendance at the pride parades has been increasing significantly since 2008, with an estimated participation of 3,500 people in Delhi and 1,500 people in Bangalore in 2010.
The NAACP, the leading African-American civil rights organization, has pledged its support for gay rights and same-sex marriage, stating that they "support marriage equality consistent with equal protection under the law provided under the Fourteenth Amendment of the United States Constitution", and has declared that same-sex marriage is a civil right.[31]
In June 2018, arguing that her right to privacy and equality had been violated, amounting to a breach of the Basic Law, and the Hong Kong Bill of Rights Ordinance; a Hong Kong lesbian woman known as "MK" filed a lawsuit against the Hong Kong Government for denying her the right to enter into a civil partnership with her female partner. The High Court heard the case in a preliminary brief 30-minute hearing in August 2018, and it is expected to be heard in the first half of 2019.[33][34][35] In April 2019, a judge rejected a bid by a Hong Kong Catholic diocese and other conservative groups to join litigation and ruled that the court can not arbitrate on social or theological issues and works only on legal considerations, as the counsel for Catholic diocese had argued outcome of court case could lead to ‘reverse discrimination’ and have chilling effect on the church. The case is scheduled to be heard on 28 May 2019.[36][37]
