Fake news. That’s how guys shed their skin. Pull foreskin down to the base of the penis, stretch it enough to step out with one leg and then the other, then pull it up over your head (the one on your shoulders, not the one on your dick) and off your hands/fingers. Shedding process complete.

UPDATE: ok, Anon answered and the theory several of you mentioned is correct. Anon is actually a girl, and she apparently thought foreskins can be peeled back all the way to the base of the penis. How she discovered this may be too horrible to contemplate though. I really hope she didn’t try to do that to some poor guy
