Acronyms

In BDSM is much talk of SSC (Sane, Safe and Consensual), but there are some initials with which I take communion too, because I think the "safe" is very elastic. Is that all practices are absolutely safe, even taking precautions, there are certain risks or inevitable?

Slave David Stein established the SSC to early 80s to somehow rule a series of practices outside the BDSM community were associated with abuse and even mental illness (someday our wonderful "paraphilias" will be discontinued as such by WHO, as has been homosexuality).

 Maybe I'm more inclined to the RACK (Risk Aware Consensual Kinks), a term coined in the 90s, where there is a possibility of risk, which is borne by all parties involved. Although, to be perfectly honest, what I really prefer is the meta-consensus, in which the submissive / slave puts his confidence in my expertise. Logically, to reach a meta-consensus is needed a consolidated relationship, then there must be a thorough understanding between the parties to enjoy the full trust.

I've developed a very broad strokes, but there is a lot to say about each of the acronyms, but I leave a general outline and would be good to investigate each in turn, as a bit of BDSM culture never hurts and so I I open a small range of possibilities.

SSC, RACK, meta-consensus ... Can you tell I always try to exceed limits? :)
