okay, so im 19, i feel abit stupid asking this but,here goes..me and my boyfriend havent had sex,but we've done other stuff, last night, he was giving himself a handjob, but was fingering me at the same time, he then swapped hands, and used the hand he was using on himself on me, he didnt ejaculate, but i dunno if he pre cummed or not, is there a possibility i could be pregnant as his fingers went into my vagina?
