My girlfriend and I were engaging in some kinky sex games recently when she started peeing whilst I was inside her. We were both really turned on by this, and now she wants me to pee whilst my penis is inside her vagina.

I am, as you can imagine, a little apprehensive about this, and would like to know if it could be a dangerous thing to do, or if it would be okay!

I can't see any harm in it, but I would be careful that no urine gets inside your penis, that could possibly cause problems, but hell there's a whole sec of people who drink urine as part of their diet. To each his own I suppose.
