Doesn't matter...: It doesn't matter how long, because the living things in healthy, normal semen are the sperm. The rest of the semen is not alive and thus does not survive nor die. Sperm on a bedsheet are out of their natural environment and can do nothing. If a sperm can do nothing, it does not matter how long it can survive. That said, the answer is yes, the sperm are dead after 24 hours, maybe after 24 minutes.
