A gentleman by the name of “ZeroTSM” has quite a few intense BDSM videos that I recommend checking out. Check them out HERE, although you may need to sign in to see them. Here’s an example of the SM videos where he’s getting whipped…. 60 times.
This video is very intense and not a suggested activity for those just getting into “pain play” (SM). I strongly recommend you trust the person you submit to 110% (get references, too) and have safe words you both agree upon.
You are right about trusting the top you play with, but a top must also trust the bottom, too. The guys in this video have been together in a relationship for a very long time and know each other (and themselves) very well.
I am enjoying your blog!
