If my husband and I have sex and he ejaculates into the condom, how long before the sperm die, if i drew the seman into a syring (no needle)! and then injected it into my vagina, how many hours do I have before they die? I really want another baby, he doesnt at the moment but he always says If I did fall pregnant, we would go ahead with the pregnancy. He came inside me several months ago when we didnt have a condom to hand. And said if we get pregnant then so be it.
