In September 2011, the Coalition Government announced its intention to introduce same-sex civil marriage in England and Wales by the May 2015 general election.[337] However, unlike the Scottish Government's consultation, the UK Government's consultation for England and Wales did not include provision for religious ceremonies. In May 2012, three religious groups (Quakers, Liberal Judaism and Unitarians) sent a letter to David Cameron, asking that they be allowed to solemnise same-sex weddings.[338]
Some transgender people's sense of difference is so strong that they identify as transsexual and believe their assigned sex at birth was wrong and that their correct sex is one that aligns with their internal feelings. They often have a deep desire to alter their physical appearance until it better matches their gender identity; two common methods of doing this include sex reassignment therapy and/or surgery.
Scientific literature indicates that parents' financial, psychological and physical well-being is enhanced by marriage and that children benefit from being raised by two parents within a legally recognized union (either a mixed-sex or same-sex union). As a result, professional scientific associations have argued for same-sex marriage to be legally recognized as it will be beneficial to the children of same-sex parents or carers.[505][43][506][507][508]
The establishment of same-sex marriage is associated with a significant reduction in the rate of attempted suicide among children, with the effect being concentrated among children of a minority sexual orientation. A study of nationwide data from across the United States from January 1999 to December 2015 revealed that the rate of attempted suicide among all schoolchildren in grades 9–12 declined by 7% and the rate of attempted suicide among schoolchildren of a minority sexual orientation in grades 9–12 declined by 14% in states which established same-sex marriage, resulting in approximately 134,000 fewer children attempting suicide each year in the United States. The researchers took advantage of the gradual manner in which same-sex marriage was established in the United States (expanding from one state in 2004 to all fifty states in 2015) to compare the rate of attempted suicide among children in each state over the time period studied. Once same-sex marriage was established in a particular state, the reduction in the rate of attempted suicide among children in that state became permanent. No reduction in the rate of attempted suicide among children occurred in a particular state until that state recognized same-sex marriage. The lead researcher of the study observed that "laws that have the greatest impact on gay adults may make gay kids feel more hopeful for the future".[135][136][137][138][139]
In what is now the United States and Canada, many Native American and First Nations peoples recognized[155] the existence of more than two genders, such as the Zuñi male-bodied Ła'mana,[156] the Lakota male-bodied winkte,[157] and the Mohave male-bodied alyhaa and female-bodied hwamee.[158] Such people were previously[159] referred to as berdache but are now referred to as Two-Spirit,[160] and their spouses would not necessarily have been regarded as gender-different.[158] In Mexico, the Zapotec culture includes a third gender in the form of the Muxe.[161]
Non-recognition of the identity of Hijras/transgender persons denies them equal protection of law, thereby leaving them extremely vulnerable to harassment, violence and sexual assault in public spaces, at home and in jail, also by the police. Sexual assault, including molestation, rape, forced anal and oral sex, gang rape and stripping is being committed with impunity and there are reliable statistics and materials to support such activities. Further, non-recognition of identity of Hijras /transgender persons results in them facing extreme discrimination in all spheres of society, especially in the field of employment, education, healthcare etc.

The Parliament approved a bill to legalise same-sex marriage on 18 June 2014.[267] The law was published in the official gazette on 17 July and took effect on 1 January 2015.[268][269][270] On 15 May 2015, Luxembourg became the first country in the European Union to have a prime minister who is in a same-sex marriage, and the second one in Europe. Prime Minister Xavier Bettel married Gauthier Destenay, with whom he had been in a civil partnership since 2010.
Polysexuality, unlike pansexuality, is the attraction to multiple genders but not all. A middle ground between bisexuality and pansexuality, it is centered more around attractions to femininity and masculinity rather than gender itself. The pink represents attraction to females; the blue for males. The green is for an attraction to those who don't conform to either gender.
Ultimately, I think the Equal Protection Clause does guarantee same-sex marriage in all fifty states. But, as you know, courts have always been strategic. There have been times where the stars were aligned and the Court, like a thunderbolt, issues a ruling like Brown v. Board of Education, but that's pretty rare. And, given the direction of society, for the Court to have allowed the process to play out the way it has may make the shift less controversial and more lasting.[111]
Barack Obama's views on same-sex marriage varied over the course of his political career and became more consistently supportive of same-sex marriage rights over time. In the 1990s, he had supported same-sex marriage while campaigning for the Illinois Senate.[102][103] During the 2008 presidential campaign, he was opposed to same-sex marriage,[104] but he also opposed the 2008 California referendum that aimed at reversing a court ruling establishing same-sex marriage there.[105] In 2009, he opposed two opposing federal legislative proposals that would have banned or established same-sex marriage nationally, stating that each state had to decide the issue.[106][107] In December 2010, he expressed support for civil unions with rights equivalent to marriage and for federal recognition of same-sex relationships. He opposed a federal constitutional amendment to ban same-sex marriage.[108] He also stated that his position on same-sex marriage was "evolving" and that he recognized that civil unions from the perspective of same-sex couples was "not enough".[109] On May 9, 2012, President Obama became the first sitting president to support same-sex marriage. He still said the legal question belonged to the states.[110] In October 2014, Obama told an interviewer that his view had changed:
Because some bisexual people do not feel that they fit into either the homosexual or the heterosexual world, and because they have a tendency to be "invisible" in public, some bisexual persons are committed to forming their own communities, culture, and political movements. However, since "Bisexual orientation can fall anywhere between the two extremes of homosexuality and heterosexuality", some who identify as bisexual may merge themselves into either homosexual or heterosexual society. Still other bisexual people see this merging as enforced rather than voluntary; bisexual people can face exclusion from both homosexual and heterosexual society on coming out. Psychologist Beth Firestein states that bisexuals also tend to internalize social tensions related to their choice of partners.[37] Firestein suggests bisexuals may feel pressured to label themselves as homosexuals instead of occupying a difficult middle ground in a culture that has it that if bisexuals are attracted to people of both sexes, they must have more than one partner, thus defying society's value on monogamy.[37] These social tensions and pressure may and do affect bisexuals' mental health.[37][38] Specific therapy methods have been developed for bisexuals to address this concern.[37]
In some cases animals will choose intercourse with different sexes at different times in their life, and sometimes will perform intercourse with different sexes at random. Homosexual intercourse can also be seasonal in some animals like male walruses, who often engage in homosexual intercourse with each other outside of the breeding season and will revert to heterosexual intercourse during breeding season.[43]
The cultures of the Indian subcontinent include a third gender, referred to as hijra in Hindi. In India, the Supreme Court on April 15, 2014, recognized a third gender that is neither male nor female, stating "Recognition of transgenders as a third gender is not a social or medical issue but a human rights issue."[153] On January 5, 2015, Reuters stated that the first transgender mayor was elected in central India.[154]
Despite their relative independence, few organizations recognize same-sex partnerships without condition. The agencies of the United Nations recognize same-sex marriages if the country of citizenship of the employees in question recognizes the marriage.[486] In some cases, these organizations do offer a limited selection of the benefits normally provided to mixed-sex married couples to de facto partners or domestic partners of their staff, but even individuals who have entered into a mixed-sex civil union in their home country are not guaranteed full recognition of this union in all organizations. However, the World Bank does recognize domestic partners.[487]

Transgender, then, unlike transsexual is a multifaceted term. One example of a transgendered person might be a man who is attracted to women but also identifies as a cross-dresser. Other examples include people who consider themselves gender nonconforming, multigendered, androgynous, third gender, and two-spirit people. All of these definitions are inexact and vary from person to person, yet each of them includes a sense of blending or alternating the binary concepts of masculinity and femininity. Some people using these terms simply see the traditional concepts as restrictive. Less than one percent of all adults identify as transgender.

The pink color represents sexual attraction to the same sex only, homosexuality, the blue represents sexual attraction to the opposite sex only, heterosexuality, and the resultant overlap color purple represents sexual attraction to both sexes (bi).
Most transgender people are banned from serving since April 12, 2019 (can only serve in basis of biological sex)[citation needed][170][171][172] / Federal executive order prohibiting discrimination based on sexual orientation for employees in the federal civilian workforce, along with government employment in the District of Columbia, and the United States Postal Service, since 1998 (see Executive Order 12968 and Executive Order 13087). Pathologization or attempted treatment of sexual orientation with minors by mental health professionals illegal in some states and territories.
Civil unions in New Jersey (2007),[163] Illinois (2011),[164] Hawaii (2012),[165] and Colorado (2013)[166] Legal in some states since 2004, nationwide since 2015[167] Legal in some states since 1993, nationwide since 2016[168] "Don't ask, don't tell" policy was abolished in 2011, meaning that since then LGB people have been allowed to serve openly in the military.[169]
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]
Civil rights campaigning in support of marriage without distinction as to sex or sexual orientation began in the 1970s.[1] In 1972, the now overturned Baker v. Nelson saw the Supreme Court of the United States decline to become involved.[2] The issue became prominent from around 1993, when the Supreme Court of Hawaii ruled in Baehr v. Lewin that it was unconstitutional under the state constitution for the state to abridge marriage on the basis of sex. That ruling led to federal and state actions to explicitly abridge marriage on the basis of sex in order to prevent the marriages of same-sex couples from being recognized by law, the most prominent of which was the 1996 federal DOMA. In 2003, the Massachusetts Supreme Judicial Court ruled in Goodridge v. Department of Public Health that it was unconstitutional under the state constitution for the state to abridge marriage on the basis of sex. From 2004 through to 2015, as the tide of public opinion continued to move towards support of same-sex marriage, various state court rulings, state legislation, direct popular votes (referendums and initiatives), and federal court rulings established same-sex marriage in thirty-six of the fifty states.

Also, in a 2008 study, its authors stated that "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" and 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."[58]

In December 2012, the state of São Paulo likewise had same-sex marriage legalized by court order.[194] Same-sex marriages also became equalized in relation to opposite-sex ones between January 2012 and April 2013 by court order in Alagoas, Ceará, Espírito Santo, the Federal District, Mato Grosso do Sul, Paraíba, Paraná, Piauí, Rondônia, Santa Catarina and Sergipe, and in Santa Rita do Sapucaí, a municipality in Minas Gerais. In Rio de Janeiro, the State Court facilitated its realization by district judges in agreement with the equalization (instead of ordering notaries to accept same-sex marriages in demand as all others).[195]
