Impossible: Female concerned about sperm in her mouth and on her breast skin and hands as potentially causal of pregnancy. This is an impossibility because a lot of sperm must encounter the opening of the vagina at the very least for even a slight chance of dashing up the vagina, through the cervix, into the uterus, and there to perhaps encounter an egg. Not to worry.
