How likely is it to get pregnant from pre cum? Me and my boyfriend were fooling around and shit and I kept my pants on for 90 percent of the time. Then he was jacking off then had his fingers in me and I don’t know if he ever switched hands and what not then I know he stuck his dick under my underwear but it never went inside me but I’m not sure how long it could have been there. But he officially came on my chest while I was kneeling on the floor and then I wiped it off swallowed some and then got dressed but how likely can I be pregnant from the grinding and fingering and jacking off that happened earlier? But I know he came on my chest because I told him that we were running out of time and was about to give up but he finally did on my chest.
