Good morning. I am writing because I am worried about a certain situation. When I was at my boyfriend's, he ejaculated on a sheet. Then he went to the bathroom to wipe himself, put on boxers and then sweatpants. We lay down for an hour, the boy was wearing tracksuits and after that hour there was a rubbing against each other between us – the boy was in boxer shorts, I was naked. I would like to ask if there were sperm on their boxers while dressing, were they able to survive that hour on their underpants, under tracksuits, and be able to fertilize? I know that sperm die quite quickly under the influence of outside conditions, but it was warm under the tracksuits. I would like to ask whether, if it was the right temperature for them, would they retain the ability to fertilize? Is there a risk of pregnancy? I realize that it sounds a bit unbelievable, but there is a lot of information on the internet and I'm just worried, it does not give me peace. Thank you in advance for your reply.
