Research suggests that, for most women, high sex drive is associated with increased sexual attraction to both women and men. For men, however, high sex drive is associated with increased attraction to one sex or the other, but not to both, depending on sexual orientation. Similarly for most bisexual women, high sex drive is associated with increased sexual attraction to both women and men; while for bisexual men, high sex drive is associated with increased attraction to one sex, and weakened attraction to the other.

On 22 May 2015, Ireland held a referendum. The referendum proposed to add to the Irish Constitution: "marriage may be contracted in accordance with law by two persons without distinction as to their sex". The proposal was approved with 62% of voters supporting same-sex marriage. On 29 August 2015, Irish President Michael D. Higgins signed the result of the May referendum into law, which made Ireland the first country in the world to approve same-sex marriage at a nationwide referendum. Same-sex marriage became formally legally recognised in Ireland on 16 November 2015.
In light of the absence of practice guidelines for lesbians, gays, and bisexual individuals for psychologists in Hong Kong, the Hong Kong Psychological Society, as both a learned society and a professional association, formed a work group in July 2011 to tackle the problem. On 1 August 2012, the Society published a position paper titled, Position Paper for Psychologists Working with Lesbians, Gays, and Bisexual (LGB) Individuals. There are 11 major guidelines in this position paper:
Perhaps because systems of religion and systems of civil authority often reflect and support each other, the countries that had reached consensus on the issue by the early 2000s tended to have a single dominant religious affiliation across the population; many such places had a single, state-sponsored religion. This was the case in both Iran, where a strong Muslim theocracy had criminalized same-sex intimacy, and Denmark, where the findings of a conference of Evangelical Lutheran bishops (representing the state religion) had helped smooth the way for the first national recognition of same-sex relationships through registered partnerships. In other cases, the cultural homogeneity supported by the dominant religion did not result in the application of doctrine to the civic realm but may nonetheless have fostered a smoother series of discussions among the citizenry: Belgium and Spain had legalized same-sex marriage, for instance, despite official opposition from their predominant religious institution, the Roman Catholic Church.
Numerous polls and studies on the issue have been conducted, including those that were completed throughout the first decade of the 21st century. A consistent trend of increasing support for same-sex marriage has been revealed across the world, often driven in large part by a significant generational gap in support. Polling that that been conducted in developed democracies in the first decade of the 21st century shows a majority of people in support of same-sex marriage. Support for legal same-sex marriage has increased across every age group, political ideology, religion, gender, race and region of various developed countries in the world.
Same-sex marriage in Sweden has been legal since 1 May 2009, following the adoption of a new gender-neutral law on marriage by the Swedish Parliament on 1 April 2009, making Sweden the seventh country in the world to open marriage to same-sex couples nationwide. Marriage replaced Sweden's registered partnerships for same-sex couples. Existing registered partnerships between same-sex couples remained in force with an option to convert them into marriages. Same-sex marriages have been performed by the Church of Sweden since 2009.

Marek Safjan, Leszek Bosek, eds. (2016). Konstytucja RP. Tom I. Komentarz do art. 1-86. Warszawa: C.H. Beck Wydawnictwo Polska. ISBN 9788325573652. Z przeprowadzonej powyżej analizy prac nad Konstytucją RP wynika jednoznacznie, że zamieszczenie w art. 18 Konstytucji RP zwrotu definicyjnego "związek kobiety i mężczyzny" stanowiło reakcję na fakt pojawienia się w państwach obcych regulacji poddającej związki osób tej samej płci regulacji zbliżonej lub zbieżnej z instytucją małżeństwa. Uzupełniony tym zwrotem przepis konstytucyjny "miał pełnić rolę instrumentu zapobiegającego wprowadzeniu takiej regulacji do prawa polskiego" (A. Mączyński, Konstytucyjne podstawy prawa rodzinnego, s. 772). Innego motywu jego wprowadzenia do Konstytucji RP nie da się wskazać (szeroko w tym zakresie B. Banaszkiewicz, "Małżeństwo jako związek kobiety i mężczyzny", s. 640 i n.; zob. też Z. Strus, Znaczenie artykułu 18 Konstytucji, s. 236 i n.). Jak zauważa A. Mączyński istotą tej regulacji było normatywne przesądzenie nie tylko o niemożliwości unormowania w prawie polskim "małżeństw pomiędzy osobami tej samej płci", lecz również innych związków, które mimo tego, że nie zostałyby określone jako małżeństwo miałyby spełniać funkcje do niego podobną (A. Mączyński, Konstytucyjne podstawy prawa rodzinnego, s. 772; tenże, Konstytucyjne i międzynarodowe uwarunkowania, s. 91; podobnie L. Garlicki, Artykuł 18, w: Garlicki, Konstytucja, t. 3, uw. 4, s. 2, który zauważa, że w tym zakresie art. 18 nabiera "charakteru normy prawnej").

Alan P. Bell, Martin S. Weinberg, and Sue Kiefer Hammersmith reported in Sexual Preference (1981) that sexual preference was much less strongly connected with pre-adult sexual feelings among bisexuals than it was among heterosexuals and homosexuals. Based on this and other findings, they suggested that bisexuality is more influenced by social and sexual learning than is exclusive homosexuality. Letitia Anne Peplau et al. wrote that while Bell et al.'s view that biological factors may be more influential on homosexuality than on bisexuality might seem plausible, it has not been directly tested and appears to conflict with available evidence, such as that concerning prenatal hormone exposure.
Religious institutions can decline to marry gay and lesbian couples if they wish, but they should not dictate marriage laws for society at large. As explained by People for the American Way, "As a legal matter, marriage is a civil institution... Marriage is also a religious institution, defined differently by different faiths and congregations. In America, the distinction can get blurry because states permit clergy to carry out both religious and civil marriage in a single ceremony. Religious Right leaders have exploited that confusion by claiming that granting same-sex couples equal access to civil marriage would somehow also redefine the religious institution of marriage... this is grounded in falsehood and deception."  Nancy Cott, PhD, testified in Perry v. Schwarzenegger that "[c]ivil law has always been supreme in defining and regulating marriage." 
In feudal Japan, homosexuality was recognized, between equals (bi-do), in terms of pederasty (wakashudo), and in terms of prostitution. The younger partner in a pederastic relationship often was expected to make the first move; the opposite was true in ancient Greece. In religious circles, same-sex love spread to the warrior (samurai) class, where it was customary for a boy in the wakashū age category to undergo training in the martial arts by apprenticing to a more experienced adult man. The man was permitted, if the boy agreed, to take the boy as his lover until he came of age; this relationship, often formalized in a "brotherhood contract", was expected to be exclusive, with both partners swearing to take no other (male) lovers. The Samurai period was one in which homosexuality was seen as particularly positive. Later when Japanese society became pacified, the middle classes adopted many of the practices of the warrior class.
Sex is what "junk" (physical sex organs) you were born with. Which is more than just chromosomes like some would like to suggest. In fact, you can not tell someone sex from sex chromosomes alone. But that's different can of worms. People assume that there are only females and males, yet there are people who are born somewhere in the middle. Or what we know has DSD or intersex.
LGBT communities in other countries have also adopted the rainbow flag. A South African gay pride flag which is a hybrid of the rainbow flag and the national flag of South Africa was launched in Cape Town in 2010. Flag designer Eugene Brockman said "I truly believe we (the LGBT community) put the dazzle into our rainbow nation and this flag is a symbol of just that." On April 20, 2017, advertising agency Ogilvy & Mather announced the release of a commemorative, rainbow-colored font named "Gilbert Color", designed in collaboration with software company Fontself. The font is freely distributed under a Creative Commons license.
Different religions have their own views about transgender and transsexual individuals, and not all religions are tolerant toward this community. There is no clear distinction of the two terms in religious texts, and, though most religions have condemned trans behavior, there are cultures and traditions that promote acceptance in some parts of the world, religion notwithstanding.
There are 1,138 benefits, rights and protections available to married couples in federal law alone, according to a General Accounting Office assessment made in 2004.  Benefits only available to married couples include hospital visitation during an illness, the option of filing a joint tax return to reduce a tax burden, access to family health coverage, US residency and family unification for partners from another country, and bereavement leave and inheritance rights if a partner dies.   Married couples also have access to protections if the relationship ends, such as child custody, spousal or child support, and an equitable division of property.  Married couples in the US armed forces are offered health insurance and other benefits unavailable to domestic partners.  The Internal Revenue Service (IRS) and the US Department of Labor also recognize married couples, for the purpose of granting tax, retirement and health insurance benefits.  The US federal government does not grant equivalent benefits to gay couples in civil unions or domestic partnerships.   An Oct. 2, 2009 analysis by the New York Times estimated that same-sex couples denied marriage benefits will incur an additional $41,196 to $467,562 in expenses over their lifetimes compared with married heterosexual couples.  A Jan. 2014 analysis published by the Atlantic concluded that unmarried women pay up to one million dollars more over their lifetimes than married women for healthcare, taxes, and other expenses. 
As noted above, many societies traditionally chose to ignore the issue of same-sex marriage by treating same-sex intimacy as a subject unsuitable for discussion. Many of these jurisdictions, as well as those that actively criminalize same-sex unions, contended that homosexuality and lesbianism are mental disorders and built their public policies on this premise. In treating same-sex desire as a psychiatric illness, these cultures moved same-sex intimacy and marriage from the realm of civil regulations (the domain of contract law) to that of public safety (the domain of criminal law). In such societies, the possibility of arrest or institutionalization further reinforced taboos on same-sex intimacy and discussions thereof, typically driving such activities underground.
Use of the rainbow flag by the gay community began in 1978 when it first appeared in the San Francisco Gay and Lesbian Freedom Day Parade. Borrowing symbolism from the hippie movement and black civil rights groups, San Francisco artist Gilbert Baker designed the rainbow flag in response to a need for a symbol that could be used year after year. Baker and thirty volunteers hand-stitched and hand-dyed two huge prototype flags for the parade. The flags had eight stripes, each color representing a component of the community.
On June 26, 2015, the US Supreme Court ruled that gay marriage is a right protected by the US Constitution in all 50 states. Prior to their decision, same-sex marriage was already legal in 37 states and Washington DC, but was banned in the remaining 13. US public opinion had shifted significantly over the years, from 27% approval of gay marriage in 1996 to 55% in 2015, the year it became legal throughout the United States, to 61% in 2019.
The Christian Democratic People's Party of Switzerland (CVP/PDC) started in 2011 with gathering signatures for a popular initiative entitled "For the couple and the family - No to the penalty of marriage". This initiative would change article 14 of the Swiss Federal Constitution and aimed to put equal fiscal rights and equal social security benefits between married couples and unmarried cohabiting couples. However, the text aimed to introduce as well in the Constitution for the first time ever the definition of marriage, which would be the sole "union between a man and a woman". On 19 June 2015, the Parliament recommended that voters reject the initiative. The Federal Council also recommended rejecting the initiative. The Swiss people voted on the Christian Democrats' proposal in a referendum on 28 February 2016 and rejected it by 50.8% of the votes.
Based in part on research that has been conducted on the adverse effects of stigmatization of gays and lesbians, numerous prominent social science organizations have issued position statements supporting same-sex marriage and opposing discrimination on the basis of sexual orientation; these organizations include the American Psychoanalytic Association and the American Psychological Association.
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 about 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".
The Showcase supernatural crime drama, Lost Girl, about creatures called Fae who live secretly among humans, features a bisexual protagonist, Bo, played by Anna Silk. In the story arc she is involved in a love triangle between Dyson, a wolf-shapeshifter (played by Kris Holden-Ried), and Lauren Lewis, a human doctor (played by Zoie Palmer) in servitude to the leader of the Light Fae clan.
In some countries, transgender people can have their gender legally recognised. However, in most cases they must endure humiliating processes, including getting a psychiatric diagnosis and undergoing irreversible sterilization, that violate their human rights. Just seven countries don’t have processes that do this. They are: Argentina, Belgium, Colombia, Denmark, Ireland, Malta and Norway.
Some scholars, most notably the Yale professor and historian John Boswell (1947–94), have argued that same-sex unions were recognized by the Roman Catholic Church in medieval Europe, although others have disputed this claim. Scholars and the general public became increasingly interested in the issue during the late 20th century, a period when attitudes toward homosexuality and laws regulating homosexual behaviour were liberalized, particularly in western Europe and the United States.
Legalizing gay marriage could lead down a "slippery slope," giving people in polygamous, incestuous, bestial, and other nontraditional relationships the right to marry.  Glen Lavy, JD, senior counsel with the Alliance Defense Fund, argued in a May 21, 2008 Los Angeles Times op-ed, "The movement for polygamy and polyamory is poised to use the successes of same-sex couples as a springboard for further de-institutionalizing marriage."  In Apr. 2013 Slate writer Jillian Keenan wrote: "Just like heterosexual marriage is no better or worse than homosexual marriage, marriage between two consenting adults is not inherently more or less 'correct' than marriage among three (or four, or six) consenting adults."  James C. Dobson, Founder and Chairman of Focus on the Family, predicted in 2005 that legalizing same-sex marriage will enable "group marriage," "marriage between daddies and little girls," and "marriage between a man and his donkey." 
Other transgender identities are becoming more widely known, as a result of contact with other cultures of the Western world. These newer identities, sometimes known under the umbrella use of the term "genderqueer", along with the older travesti term, are known as non-binary and go along with binary transgender identities (those traditionally diagnosed under the now obsolete label of "transsexualism") under the single umbrella of transgender, but are distinguished from cross-dressers and drag queens and kings, that are held as nonconforming gender expressions rather than transgender gender identities when a distinction is made.
Gilbert Baker, an openly gay activist born in 1951, grew up in Parsons, Kansas, and went on to serve in the US army for about two years around 1970. After an honorable discharge, Gilbert taught himself to sew. In 1974, Baker met Harvey Milk, an influential gay leader, who three years later challenged Baker to come up with a symbol of pride for the gay community. The original gay pride flag flew at the San Francisco Gay Freedom Day Parade celebration on June 25, 1978. It has also been suggested that Baker may have been inspired by Judy Garland's singing "Over the Rainbow" and the Stonewall riots that happened a few days after Garland's death (she was one of the first gay icons). Another suggestion for how the rainbow flag originated is that at college campuses during the 1960s, some people demonstrated for world peace by carrying a Flag of the Races (also called the Flag of the Human Race) with five horizontal stripes (from top to bottom they were red, white, brown, yellow, and black). The first rainbow flags were commissioned by the fledgling pride committee and were produced by a team led by Baker that included artist Lynn Segerblom. Segerblom was then known as Faerie Argyle Rainbow; she created the original dyeing process for the flags. Baker is said to have gotten the idea for the rainbow flag from the Flag of the Races in borrowing it from the Hippie movement of that time largely influenced by pioneering gay activist Allen Ginsberg. The flag originally comprised eight stripes; Baker assigned specific meaning to each of the colors:
Some bisexuals make a distinction between gender and sex. Gender is defined in these situations as a social or psychological category, characterized by the common practices of men and women. For example, the fact that women wear skirts and dresses in Western society while men traditionally do not is a social gender issue. Sex in this case is defined as the biological difference between males and females, prior to any social conditioning. Bisexuals in this sense may be attracted to more than one gender but only to one sex. For example, a male bisexual may be attracted to aspects of men and masculinity, but not to the male body.
External manifestations of gender, expressed through a person's name, pronouns, clothing, haircut, behavior, voice, and/or body characteristics. Society identifies these cues as masculine and feminine, although what is considered masculine or feminine changes over time and varies by culture. Typically, transgender people seek to align their gender expression with their gender identity, rather than the sex they were assigned at birth.
In 2010, a Columbia University Mailman School of Public Health study examining the effects of institutional discrimination on the psychiatric health of lesbian, gay and bisexual (LGB) individuals found an increase in psychiatric disorders, including a more than doubling of anxiety disorders, among the LGB population living in states that instituted bans on same-sex marriage. According to the author, the study highlighted the importance of abolishing institutional forms of discrimination, including those leading to disparities in the mental health and well-being of LGB individuals. Institutional discrimination is characterized by societal-level conditions that limit the opportunities and access to resources by socially disadvantaged groups.
The 1950s and 1960s in the United States was an extremely repressive legal and social period for LGBT people. In this context American homophile organizations such as the Daughters of Bilitis and the Mattachine Society coordinated some of the earliest demonstrations of the modern LGBT rights movement. These two organizations in particular carried out pickets called "Annual Reminders" to inform and remind Americans that LGBT people did not receive basic civil rights protections. Annual Reminders began in 1965 and took place each July 4 at Independence Hall in Philadelphia.
By the late 1970s and early 1980s, as many of the actual participants had grown older, moved on to other issues or died, this led to misunderstandings as to who had actually participated in the Stonewall riots, who had actually organized the subsequent demonstrations, marches and memorials, and who had been members of early activist organizations such as Gay Liberation Front and Gay Activists Alliance. The language has become more accurate and inclusive, though these changes met with initial resistance from some in their own communities who were unaware of the historical events. Changing first to Lesbian and Gay, today most are called Lesbian, Gay, Bisexual and Transgender (LGBT) or simply "Pride".

Bevan, The Psychobiology of Transsexualism and Transgenderism (2014, ISBN 1-4408-3127-0), page 42: "The term transsexual was introduced by Cauldwell (1949) and popularized by Harry Benjamin (1966) [...]. The term transgender was coined by John Oliven (1965) and popularized by various transgender people who pioneered the concept and practice of transgenderism. It is sometimes said that Virginia Prince (1976) popularized the term, but history shows that many transgender people advocated the use of this term much more than Prince."
Marriage is an outmoded, oppressive institution that should be weakened, not expanded. LGBT (lesbian, gay, bisexual, and transgender) activist collective Against Equality states that "Gay marriage apes hetero privilege... [and] increases economic inequality by perpetuating a system which deems married beings more worthy of the basics like health care and economic rights."  The leaders of the Gay Liberation Front in New York said in July 1969, "We expose the institution of marriage as one of the most insidious and basic sustainers of the system. The family is the microcosm of oppression."  Self-described queer activist Anders Zanichkowsky stated in June 2013 that the campaign for gay marriage "intentionally and maliciously erases and excludes so many queer people and cultures, particularly trans and gender non-conforming people, poor queer people, and queer people in non-traditional families... marriage thinks non-married people are deviant and not truly deserving of civil rights." 
Ancestral law in ancient Sparta mandated same-sex relationships with youths who were coming of age for all adult men, so long as the men eventually took wives and produced children. The Spartans thought that love and erotic relationships between experienced and novice soldiers would solidify combat loyalty and encourage heroic tactics as men vied to impress their lovers. Once the younger soldiers reached maturity, the relationship was supposed to become non-sexual, but it is not clear how strictly this was followed. There was some stigma attached to young men who continued their relationships with their mentors into adulthood. For example, Aristophanes calls them euryprôktoi, meaning "wide arses", and depicts them like women.
There is no complete data on the number of same-sex marriages conducted in the United States. Marriages and divorces are recorded by states, counties, and territories, plus New York City and the District of Columbia, but not by the federal government. States such as Oregon do not distinguish between opposite-sex and same-sex marriages in their official records. The legal records on marriage and divorce belong to the states. In August 2016, the Treasury Department estimated the number of same-sex marriages by linking the tax returns of same-sex couples who had filed jointly in 2014 with their Social Security records. (Although this method excluded couples who file singly, these are small in number; of all married couples who file taxes, 97.5% file jointly.) This research showed that in 2014 there were about 183,280 married same-sex couples in the country, or "roughly a third of 1 percent of all marriages" according to the New York Times.
