I totally get the fantasy when one is just watching a fight or a scene.
I have also heard that in the actual physical receiving end of things, one could actually get off on treading that balance between pain and pleasure. The last time I had a BDSM session was with 2 repeat providers and it got a little too rough (in my opinion) and I was gagged (and totally forgot to get aligned on a safe word), so that was something ?♂️. Is it more of a trial-an-error thing, but if it is, how does one gauge what that pain vs. pleasure tolerance level to want to be beat up a little before one just completely gets turned off by the whole thing?
