Hello,I´ve searched for an answer in many sites but none of them has given me any return.I really apreciate for your atention.I am really concerned about a situation: i slept with a girl last week but she was menstruating. So, actually, we did not have sex. She was wearing bikini and i was wearing shorts and underwear. So she started rubbing her vagina on my penis for several minutes. We kept our clothes on all the time. Now, i am afraid some blood or vaginal fluid may came into contact with my penis. Do i have any chance of contract HIV like this?? Thank you so much for your atention.
