Just so you know, this thread is not about the Biblical submission of a wife to her husband.
It is about BDSM. This stands for Bondage and Discipline, Dominance and Submission and Sadism and Masochism.
"
BDSM is a variety of
erotic practices involving
dominance and submission,
roleplaying,
bondage, 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."
"
BDSM has become an umbrella term for certain kinds of erotic behavior between consenting adults. There are various
subcultures under this umbrella term and distinct differences between these subcultures. Terminology for roles varies widely within the various BDSM subcultures.
Top and
dominant are widely recognized for those partner(s) in the relationship or activity who are, respectively, the physically active or controlling participants.
Bottom and
submissive are widely recognized terms for those partner(s) in the relationship or activity who are, respectively, the physically receptive or controlled participants. The interaction between tops and bottoms—where physical or mental control of the bottom is surrendered to the top—is sometimes known as "power exchange", whether in the context of an encounter or a relationship."
