hi there, so me and my boyfriend were dry humping 2 days ago. There were 4 layers between us but we are both unsure if he pre-came or even ejaculated. He says his jeans were not wet but he is not sure if his boxers were. My underwear was wet but I think that was from me. If he did pre-cum or even ejaculate, the sperm wouldn’t live long enough would it? Also he was rubbing against my clitoris and wasn’t near the opening of my vagina, so.... there isn’t a chance that I could be pregnant....right? I am extremely worried and my period is due in 3 days. Advice would be appreciated. Thank you.
