Bondage– Physically restraining a partner in some way (tying someone down, handcuffs, etc.) Discipline– Giving physical or psychological punishment to control behavior.
Sadist/Masochist-- Sexual sadism is deriving pleasure from inflicting physical or psychological pain on someone else. But it’s not the same as pure sadism. A sexual sadist only enjoy inflicting the pain because the partner is a masochist and derives pleasure from receiving it. It’s an exchange of mutually pleasurable activities.
Dominance/Submission (or D/s): This is the power exchange between partners, whereby one partner (the submissive) gives over all the control to the other (the dominant). This may be only in their sexual relationship or it may be in all aspects of the relationship. Also, don’t assume that the submissive partner is always the woman. Though that’s the more popular theme , men can be submissive too.
SSC (Safe, Sane, Consensual) or RACK (Risk-Aware Consensual Kink) – These are the cornerstone philosophies in BDSM play. All activities must be consensual and safe.
Safe words – A word is given to the submissive to signal “stop everything right now”. The words “no” or “stop” aren’t typically used as safe words because sometimes in BDSM play, someone may say “no” as part of the scene. When the sub says that word, everything stops immediately, no questions asked.
Subspace – The intense experiences of both pain and pleasure trigger a sympathetic nervous system response, which causes a release of epinephrine…as well as a dump of endorphins... These natural chemicals…produce the same effect as a morphine-like drug, increasing the pain tolerance of the submissive as the scene becomes more intense. Since the increase of hormones and chemicals produces a sort of trance-like state, the submissive starts to feel out-of-body, detached from reality, and as the high comes down, and the parasympathetic nervous system kicks in, a deep exhaustion, as well as incoherence.”
So when people looking from the outside in wonder why the heck someone would want to be tied up, flogged, and bossed around---well, there you go, subspace is one enticing reason why.
