BDSM is a general term wich refers to a wide range of activities and forms of alternative personal and sexual relationships. The term BDSM is derived from the terms Bondage and Discipline (B&D), Domination and Submission (D&S, D/s, or Ds), Sadism and Masochism (S&M or SM). BDSM activities usually involve one person - the submissive or bottom - voluntarily giving up control to another person - the Dominant or Top. BDSM activities will often appear forced, unconsential or coerced. But in reality these roles are "played" with the full consent of all people involved. BDSM activities can include forms of dominance, submission, discipline, punishment, spanking, bondage, slave training, inflicting pain, humiliation, sexual roleplaying, sexual fetishism, kinky sex, cuckolding, sadomasochism and power exchange. Both the Dominant and submissive experience pleasure (sexual and/or nonsexual) from playing their roles.
