Reproduction must happen in a moist place. So in order for pregnancy to occur sperm must penetrate the egg inside of the female. If no sperm even made it inside of her then there is no possibility that she could be pregnant. Sooo the answer to your question is, it is impossible!
It's next to impossible. Lol
Sperm does not die when it hits the air ..it can live up to a couple hours outside the body because sperm is protected by semen..as for your girlfriend being pregnant very unlikely cause the sperm would have to be inside her vagina to be able to travle thus getting her pregnant so its highly unlikely.
theirs a very small chance but if sperm hit the air the sperms died so I wouldn't worry about it
Nope. Cant happen there has to be penetration.
