Transgender history - Wikipedia
A person may be considered to be a transgender person if their gender identity is inconsistent or not culturally associated with the sex they were assigned at birth and consequently also with the gender role and social status that is typically associated with that sex. They may have, or may intend to establish, a new gender status that accords with their gender identity. Transsexual is generally considered a subset of transgender ,    but some transsexual people reject being labelled transgender. Globally, most legal jurisdictions recognize the two traditional gender identities and social roles, man and woman , but tend to exclude any other gender identities and expressions. However, there are some countries which recognize, by law, a third gender.
Legal status of transgender people
A trans woman is a woman who was assigned male at birth. Trans women may experience gender dysphoria and may transition ; this process commonly includes hormone replacement therapy and sometimes sex reassignment surgery , which can bring relief and resolve feelings of gender dysphoria. Trans women may be heterosexual , bisexual , homosexual , asexual , or identify with other terms such as queer. The term transgender woman is not always interchangeable with transsexual woman , although the terms are often used interchangeably.
Homosexual transsexual is a taxonomic category of transsexual individuals used in sexology , psychology , and psychiatry. It categorizes trans women who are exclusively attracted to men, and less often trans men who are exclusively attracted to women, based on their sex assigned at birth , rather than their current gender identity. The concept of categorizing trans women by sexual orientation originated with Magnus Hirschfeld in , and was further developed by the sexologist Harry Benjamin in as a component of the Benjamin scale. The specific term homosexual transsexual was coined by Kurt Freund in , and used from onward by him and others. In the DSM III , published in , transsexualism was to be diagnosed and the sexual orientation of a transsexual specified using the terms homosexual , heterosexual , asexual , or unspecified.
