The other day my boyfriend and I were cuddling, which evolved into a mutual masterbation session. He didnt come, but he whiped some of his precum off on his jeans with his finger, the same finger which he later put inside me. I know that you can get pregnant from precum, and that it only takes one sperm, so I was wondering what my chances of getting pregnant are from that. Hopefully i'm just overly paranoid. :?
