If a man cums/ejaculates inside of you can get pregnant. The previous posts states that she is on the pill and she hasn't...good for her. But remember pills nor condoms aren't 100% neither. Why are people so foolish and think they are? The position does not matter. Days after the sex is over the sperm still lives within the woman 5-7 days after. Yes, its true and you're talking about 40 million of them (sperm) trying to find their way to that egg. Please be safe, read, study, and don't be sorry. Hope this helps
