On Wednesday night I wanked partner on himself, he just wiped of with tissue and we went back to sleep him spooning me. A few hours later he is horny again and starting rubbing himself on me ( had thong on ) but with being half asleep I don't know if it was on top of my pants or on my skin, he definitely didn't go inside. I feel stupid ( hope I'm just worried for nothing. ) for asking but is it possible to become pregnant like that?
