Hello, my girlfriend and I have just started to have intercourse. Whenever she is on the bottom she always feels like shes going to pee and then she has to run to the restroom and then runs back and we start again..... then after awhile she gets the feeling again. I have heard in a sexuality class that many women feel this but they will not actually pee. I was wondering if this is true. Is kinda hard for me to tell her exactly whats going on in her body (i would question her telling me whats happening to me in a similar situation). I'm asking this really for her more than me. If someone can point me towards more information or how I should approach her about it I would greatly appreciate it.

thanks
