My boyfriend and I were messing around a bit and he came all over his stomach when he masturbated. Also, I helped him clean up with a towel but he had sperm all over his hands and dried it off. About 10 minutes later I was still in my underwear but my vagina was wet and it was wet through my underwear and he fingered me through the outside of my underwear but pushed his fingers in with my underwear if that makes sense. Could I get pregnant from that?
