I gave my boyfriend a blowjob. But he wanted me to let him cum on my face. So I finished with my hand. His cum was all over his penis and a few places a condom wouldn't over. I licked all that was visible off. Then a few minutes later he put a condom on and we had sex. He didn't ejaculate inside me though. How likely is it that I could be pregnant?
Semen can't survive for long in open air, as they need a warm, moist environment to survive. From what you say, it's likely that any semen that may have been on you or him had died before you engaged in vaginal sex.
