Me and my bf were dry humping, he wasn't wearing underwear but I was. I kept getting wedgies and his penis didn't penetrate me, but I was grinding on it while I had wedgies (the underwear blocked my vagina). I'm worried that precum might've gotten outside of my vagina or inside it in a way. We also had the AC directly on us bc it was too hot. Despite him saying that he didn't precum during the humping because he would know, would I get pregnant from this?
