Can sperm travel through fabric

Hopefully this addresses your concerns, please leave comments if you have additional questions. While rather low, this is still a non-zero chance. Skin is also a toxic environment on its own, so these improbable sperm have a very limited time to find their way. Sperm could drip near your vulva and, subsequently, your vagina if you came into contact with semen, but even that would require some interesting physics to get you pregnant, so you are most likely fine. As far as dry humping is concerned, there's no realistic reason to worry about pregnancy. Expert Activity. As for the towel some people use to wipe up semen after sex, that's pretty much the last place sperm wants to be, so it will die by the time the semen dries and definitely after a few hours.
