No, a girl can not get pregnant without the presence of sperm.
sperm doesnt expire it just helps if you use a condom so that when you decide to have sex you dont have the sperm inside you trying to fertilize your eggs .
no because girls dont have sperm and sperm is needed to make a baby.
It depends on where you are when you do ejaculate. If you are still close enough to the vagina, then there is a chance of some sperm finding their way.
If the sperm goes in a girl's body, they will get pregnant soon. but if in a guy's body, i dont know. lol :)
Sometimes a woman's egg doesnt get fertilized by the sperm. So your not pregnant.
It releases n it will stop on its own it should if it dont see a doctor
Steriods make your sperm count go down, but dont stop it all together, so yes you can .
if he came inside you then you could pregnent but if he didnt then you dont have to worry about it.
