I had just given my SO a handjob and he came all over his hands. He wiped them off on a sweatshirt (gross I know but we were in the car) and then fingered me maybe five minutes later. Since the cum was exposed to air and then mostly wiped away, it couldn't still get me pregnant, right? I do take birth control pills and I've taken them on time every single night until tonight because I left them at home. Also if for some weird reason that could get me pregnant, would I be safe considering I took my BC pill last night but not tonight after the fact? Sorry for the strange (and probably obvious) question, but I've never had that happen before.
