性同一性
The word "transgender" usually has a narrower meaning and different connotations, including an identification that differs from the gender assigned at birth. GLAAD (formerly the Gay and Lesbian Alliance Against Defamation)'s Media Reference Guide defines "transgender" as an "umbrella term for people whose gender identity or gender expression differs from the sex they were assigned at birth." Not all gender-variant people identify as transgender, and not all transgender people identify as gender-variantmany identify simply as men or women. Gender identity is one's internal sense of their own gender; while most people have a gender identity of a boy or a man, or a girl or a woman, gender identity for other people is a more complex experience.
