Cross-dresser in the context of Social aspects of clothing

A transgender (often shortened to trans) person has a gender identity different from that typically associated with the sex they were assigned at birth. The opposite of transgender is cisgender, which describes persons whose gender identity matches their assigned sex.

Many transgender people desire medical assistance to medically transition from one sex to another; those who do may identify as transsexual. Transgender does not have a universally accepted definition, including among researchers; it can function as an umbrella term. The definition given above includes binary trans men and trans women and may also include people who are non-binary or genderqueer. Other related groups include third-gender people, cross-dressers, and drag queens and drag kings; some definitions include these groups as well.

BDSM is a variety of often erotic practices or roleplaying involving bondage, discipline, dominance and submission, sadomasochism, and other related interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves to be practising BDSM, inclusion in the BDSM community or subculture often is said to depend on self-identification and shared experience.

The initialism BDSM is first recorded in a Usenet post from 1991, and is interpreted as a combination of the abbreviations B/D (Bondage and Discipline), D/s (Dominance and submission), and S/M (Sadism and Masochism). BDSM is used as a catch-all phrase covering a wide range of activities, forms of interpersonal relationships, and distinct subcultures. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers, body modification enthusiasts, animal roleplayers, rubber fetishists, and others.
