Clearly a troll post
However, for the record, one of my previous partners, a few years ago, also used to like this. I didnt pee, 'inside' the vagina, she used to hold open the outer fleshy part, not sure what that is called(not the labia) and I would pee on the inner, now visible part (it was a domination thing she got off on). We never had any problems with infections or anything. I am always very hydrated, and made a particular effort to drink extra water prior to something like this (wee was a pale/clear colour, not dark yellow/smelly).
