Hi there! I want to tell you something about sperm. It is very fragile and it dies quickly and moves very slowly. It needs semen and moisturized cervix and uterus to get to the Fallopian tubes where it is supposed to meet the egg. SO, there is no way that the pregnancy can occur while *** or precum inside cloths. Plus, there is no sperm in precum unless a boy hasn’t ejaculated once before and not washed his penis. But even then, there could be just a small amount of sperm.
