how long could sperm survive on a hand that has been wiped off but not washed? . if semen ended up on a hand that was then wiped on clothes/sheets (and no longer appeared or felt wet) and then a few minutes later that hand was inserted into a vagina what are the odds that there would be any viable sperm left and there would be any risk of pregnancy?
the odds of an unintentional pregnancy would be very very low.
