PukkaBDSM

Sadists enjoy inflicting pain; this may or may not be sexual in nature. Masochists enjoy receiving pain, which again may or may not be sexual. The simple desire for pain is technically known as algolagnia.

BDSM is a short-hand abbreviation for many subdivisions of the culture: B&D (bondage and discipline), D/s (domination and submission), S&M (sadism and masochism).

Dominance and submission is control over another or being controlled by another, respectively. Typically describes a relationship power dynamic rather than a set of acts, and may or may not involve sadomasochism. Bondage and discipline describes a set of acts that sometimes involve D/s or S&M; although discipline often implies a level of suffering (real or pretend), participants may stop short of causing actual pain.
