I had sex today with my boyfriend. We didn’t use protection. He pulled out, a few hours, maybe 2-3 hours later, we went another round without protection. Are there any chances of pregnancy (not because of unprotected sex, but the dry sperm on his penis)? Never learned this, and couldn’t find much information when researching. any help or advise would be appreciated! thanks ladies (and gents!).

PS my ovulation day is in two days. i’m aware of sperm living in bodies. i’m just not too sure about sperm survival rate outside the body. I know it thrives in hot wet places, today was pretty hot where i am, sweat? discharge? etc. idk. lmk!!
