Why I choose never apply the sadism? It's simple cuz implies too much risk in a non controlled ambient and if both parts are not in control the roleplay can finish in severe injuries included the decease of one of the partners. It's a risky roleplay that's why I prefer the safety of the sub before my fun.

I only practice the sadism but only the safe stuff that's means I use a very moderated part of the sadism what is safe like spanks,slaps and softcore stuff but never asphyxia or strangle cuz that are dangerous roleplays
