Sitting on the edge of a sofa and receiving oral pleasure from a lady, will the sofa pressure damage muscles behind scrotum at orgasm?

No matter how or where you sit while having an orgasm it will not tear the "orgasm" muscles of your perineum enough to tear them. It would take far more strain than that.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
