Transgender is a complex term that can mean many things. A trans woman - someone born male who identifies as a woman - is transgender. A trans man - someone born female who identifies as a man - is also transgender.
So is a person who doesn't identify as exclusively masculine or feminine. Sometimes these people feel that they belong to a third gender, neither male nor female.
Transgender is not a sexual orientation, like being gay, lesbian, or bisexual. It's about how you feel, not who you're attracted to. A transgender person may be attracted to men, women, or both.
Transgender is not a style. If a man chooses to wear women’s clothes, that doesn’t mean he’s transgender or a hijra – some people like wearing clothes associated with the opposite gender, but they don’t identify as that gender.
There have been transgender people in every culture, throughout history. Transgender people usually dress and behave like the gender they identify with, or an extreme version of it.
Transgender covers a wide range of identities and behaviours, especially in India where the hijra is such a well-known social figure. This is only a very short introduction to the complexity of the transgender world. For more information, you can contact the organisations listed below.
