The leather subculture denotes practices and styles of dress organized around sexual activities. Wearing leather garments is one way that participants in this culture self-consciously distinguish themselves from mainstream sexual cultures. Leather culture is most visible in gay communities and most often associated with gay men ("leathermen"), but it is also reflected in various ways in the gay, lesbian, bisexual, and straight worlds. Many people associate leather culture with BDSM (Bondage/Discipline, Dominance/Submission, Sado/Masochism, also called "SM" or "S&M") practices and its many subcultures. But for others, wearing black leather clothing is an erotic fashion that expresses heightened masculinity or the appropriation of sexual power; love of motorcycles and independence; and/or engagement in sexual kink or leather fetishism.
