BDSM is a variety of
erotic practices or
roleplaying involving
bondage,
dominance and submission,
sadomasochism, and other interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves as practicing BDSM, inclusion in the BDSM community or subculture is usually dependent on
self-identification and shared experience. Interest in BDSM can range from one-time experimentation to a lifestyle.
