BDSM is any of a number of related patterns of human sexual behavior. The
major subgroupings are described in the abbreviation "BDSM" itself:
Bondage & discipline (B&D)
Domination & submission (D&S)
Sadism and masochism (or sadomasochism) (S&M)
Many of the specific practices in BDSM are those which, if performed in neutral
or nonsexual contexts, could be considered unpleasant, undesirable or abusive.
For example, while pain, physical restraint and servitude are traditionally
inflicted on persons against their will and to their detriment, in BDSM, these
activities are engaged in with the mutual consent of the participants, and
typically for mutual enjoyment. Any "consent" may or may not amount to legal
consent and represent a defense to criminal liability for any injuries caused.
This emphasis on informed consent and safety is also known as SSC (safe, sane
and consensual), though others prefer the term RACK (risk-aware consensual
kink), believing that it places more emphasis on acknowledging the fact that all
activities are potentially risky. There is discussion and dispute about the
meaning or intent of the terms, but in essence, both terms refer to all
participants acknowledging and accepting some level of risk.
BDSM may or may not involve sex of any kind.
BDSM may or may not involve sexual roleplaying.
How dominant or submissive a person may be in their regular life does not
necessarily indicate which role they will play in a scene.
Some BDSM players are polyamorous or sexually monogamous but engage in
non-sexual play with others.
A couple may engage in BDSM sexuality with an otherwise non-Dominant/submissive
