Sperm can live for x amount of time in the air I think it's like an hour or so but I do know it can live for a while you might google it. But anyways I doubt you are pregnant it's very unlikely but be more careful next time.
If Sperm dies as soon as it touches the air then how do they contain sperm for sperm banks? not being a smart booty just curious :)
Sperm dies as soon as it touches the air you're fine.
