Inffection

Patient: I get tot see my girlfriend everymonth, and everytime we have sex and I come inside of her, it gives her an infections, why is that? I dont have any medical problems, and the last time we went to a gynecologist we were told it was due to the fact that she has one of those things so that she doesnt get pregnant in her vagina, and either I go too deep or the sex is too rought, so that can cause a bleeding..

Doctor:
