Well, I think she is not really shy about having to pee, maybe just about exposing herself in public. She is very shy about other bodily functions though, but I think I can't talk about it on this forum although I have a really good story.
I cannot remember that I have every seen her "hot party girl side" besides the fact that she likes to dance and drink a few beers here and there. The only other mum we went out with was even more tame since she hardly drank at all and also wasn't too much fun in my opinion.
