The majority of the things that I say, all of my roleplays, usually have a fantasy base.
SSC:
Safe: Technically nothing in this world is safe, because as humans, we need the thrill and adrenaline, so in knowing this remember that its called "safer sex," not "safe sex." If you want to go the safe route in BDSM, you can't really do anything more then flog your partner with a wet noodle.
Sane: Is having the ability to distinguish fantasy from reality while in sexual roleplay. Its also part of the reason why I say, do not have sex while under intoxication from alcohol or drugs.
Consensual:is the crux, implying negotiation, which implies being able to distinguish fantasy from reality, as well as dealing responsibly with risk factors. If you don't know the risk factors, or you don't know what will happen in reality, then you don't know what you're consenting to. Meaningful negotiation must always take place on the common ground of consensus reality.
RACK:
Risk-aware: both parties to a negotiation have studied the proposed activities, are informed about the risks involved, and agree how they intend to handle them.
Consensual: Please see Consensual under SSC.
Kink: We all know what kink means, but before even starting out the play you and your partner will be acting out, remember to talk, Talk, TALK, about what will happen first. Kink is a transformation of atrocity into ecstasy. According to our society, we all have non-politically correct fantasies, meaning that Kink is not widely accepted upon by our peers or government because it is outside of the normal safe, sane, and consensual sex. But when participating in a BDSM relationship where Kink is apart of it, you know that it is acted them out responsibly and consensually.
As a side note, I have studied BDSM, B/D, D/S, S/M, SSC, and RACK. Some of my words are actual definitions that have been copyrighted - because I have read them so often, I have no other way of explaining them or trying to put them into my own words.
