OK I got a question for all the members on the board.
I have got this thing I am doing lately with my GF when we have sex.
We will tie a rope around the base of my balls, using a slip knot so it easily tightens and loosens when need be. While we are having sex she pulls on the rope stretching and pulling on my balls. She also threatens to pull them off and that really gets me going. So the question I have; is what are the dangers involved in this?
For those interested the rope is one of those small white clothes lines from Wal-mart.
