wo days ago, my boyfriend ejaculated on his stomach. He wiped it off with Kleenex and we cuddled and fell asleep. However, I was not wearing underwear, and there was a time when my vulva came into contact with his stomach. I'm not sure how long it was. I want to say it was at least 5-10 minutes, though. Also I am on the pill. Is there a chance I can get pregnant?
