How long do sperm cells survive on the hands if they have been wiped? Does wiping the sperm on e.g bedding kill it all? Also, say you had a dry hand, which had sperm on that you wiped off, could there still be sperm there that possibly survived that you just can't see? Say you had sperm on your hands, does going in cold temperatures like outdoors kill them? How long do they live on hands if breifly wipe them? Has anyone ever got pregnant from dry fingers inserted into the vagina that had sperm on? Does dry hands=no sperm left on hands? So so worried. Thanks in advance!
