Gender identity and sexual orientation are not the same. Sexual orientation, according to the American Psychological Association, refers to an individual’s enduring physical, romantic, and/or emotional attraction to another person. Transgender people may be straight, bisexual, lesbian, gay, or asexual. Biological factors such as prenatal hormone levels, genetics, and early childhood experiences may all contribute to the development of a transgender identity, according to some researchers.
HKADCP's Code of Ethics ensures the HKADCP Registered Clinical Psychologists avoid discrimination in all forms and are sensitive to power differentials in dealing with current and former clients, employers, employees, and peers by striving to protect individuals who may be in a position of lower power. They are particularly sensitive to the needs of underprivileged and otherwise vulnerable individuals.
In the United States the question of whether couples of the same sex should be allowed to marry has roiled politics since at least 1993. In that year the Supreme Court of Hawaii heard a case in which the plaintiffs claimed that the state’s refusal to issue marriage licenses to same-sex couples abrogated those individuals’ rights to equal treatment under the law. The state, in turn, argued that it had a compelling interest in preventing same-sex marriage, as that practice would inherently damage the public good. The court found for the plaintiffs, basing its argument on the law’s absence of a clear definition of who might or might not participate in such a partnership. Soon after this finding, Hawaiian legislators added such a definition to the state constitution and thus made moot the issuing of marriage licenses to same-sex partners.
After analyzing the data the authors found different patterns between the gay, bisexual, and heterosexual men. The gay identified men had strong self-reported and physiological arousal to the videos to two men having sex. The heterosexual men showed the opposite pattern of arousal to the videos of two women having sex. The bisexual men also tended to show a physiological arousal that was stronger for videos with women or men. On average the bisexual men tended to be more aroused by male than female stimuli. But it is very important to point out that not all bisexual men showed this pattern. Some of the bisexually identified men showed more arousal to the female videos. In contrast to the physical measure of arousal, the bisexual men tended to show more equal self-reported arousal to both the male and female videos. The authors of the study reached the controversial conclusion that "with respect to sexual arousal and attraction, it remains to be shown that male bisexuality exists. Thus future research should also explore nonsexual reasons why some men might prefer a bisexual identity to a homosexual or heterosexual identity."
One of the largest scale uses of social media to mobilize support for same-sex marriage preceded and coincided with the arrival at the U.S. Supreme Court of high-profile legal cases for Proposition 8 and DOMA in March 2013. The "red equal sign" project started by the Human Rights Campaign was an electronic campaign primarily based on Facebook that encouraged users to change their profile images to a red equal sign to express support for same-sex marriage. At the time of the court hearings, an estimated 2.5 million Facebook users changed their profile images to a red equal sign.
Ranging from solemn to carnivalesque, pride events are typically held during LGBT Pride Month or some other period that commemorates a turning point in a country's LGBT history, for example Moscow Pride in May for the anniversary of Russia's 1993 decriminalization of homosexuality. Some pride events include LGBT pride parades and marches, rallies, commemorations, community days, dance parties, and large festivals.
As a British colony, Hong Kong's criminal laws against male homosexual acts were initially a reflection of British law, with a maximum sentence of life imprisonment. During the 1970s and 1980s, there was a public debate about whether or not to reform the law in line with human rights principles. As a result, in 1991 the Legislative Council agreed to decriminalise private, adult, non-commercial, and consensual homosexual relations.
While there is no doubt that the LGBTI movement has made significant progress, there is still work to do. Amnesty helps activists around the world by producing resources on various issues that affect LGBTI people, such as an advocacy toolkit that can be used to combat discrimination in Sub-Saharan Africa and the Body Politics series aimed at increasing awareness around the criminalization of sexuality and reproduction.
In California, the School Success and Opportunity Act authored by Assemblyman Tom Ammiano, which became state law on January 1, 2014, says "A pupil shall be permitted to participate in sex-segregated school programs and activities, including athletic teams and competitions, and use facilities consistent with his or her gender identity, irrespective of the gender listed on the pupil's records."
Ability or desire to create offspring has never been a qualification for marriage. From 1970 through 2012 roughly 30% of all US households were married couples without children, and in 2012, married couples without children outnumbered married couples with children by 9%.  6% of married women aged 15-44 are infertile, according to the US Centers for Disease Control and Prevention.  In a 2010 Pew Research Center survey, both married and unmarried people rated love, commitment, and companionship higher than having children as "very important" reasons to get married, and only 44% of unmarried people and 59% of married people rated having children as a very important reason.  Several US presidents never had their own biological children, including George Washington, often referred to as "the Father of Our Country."   As US Supreme Court Justice Elena Kagan noted, a marriage license would be granted to a couple in which the man and woman are both over the age of 55, even though "there are not a lot of children coming out of that marriage." 
What does all this mean for our understanding of bisexuality? Dictionary definitions of bisexuality that rely on an idea of “both sexes” are inadequate. As human beings, we live and love in a world that is far more complicated than these narrow ideas allow. Our attractions do not stay within tidy borders, and our understanding of bisexuality must adapt to this. Every one of us must make sense of our own experiences and assign to them our own meaning.
Historically, bisexuality has largely been free of the social stigma associated with homosexuality, prevalent even where bisexuality was the norm. In Ancient Greece pederasty was not problematic as long as the men involved eventually married and had children. In many world cultures, homosexual affairs have been quietly accepted among upper-class men of good social standing (particularly if married), and heterosexual marriage has often been used successfully as a defense against accusations of homosexuality. On the other hand, there are bisexuals who marry or live with a heterosexual partner because they prefer the complementarity of different sexes in cohabiting and co-parenting but have felt greatly enriched by homosexual relationships alongside the marriage in both monogamous and "open" relationships.
