BDSM is a variety of erotic practices involving dominance and submission, roleplaying, restraint, 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.
