I wasn't circumcised and I always seem to have the same problem with any condom I buy, when my foreskin starts rolling back and forth over the head (the way it normally should) the bottom that's supposed to be on my shaft slowly but surely starts rolling up. This happens no matter what size or style condoms I use. It's never slipped off during sex but I'm starting to think that if I didn't pay attention to it for a long time it might be able to do so. I'm sure it's the foreskin tugging the whole rubber up little by little, does that mean I have to put it on in a way that doesn't let my foreskin roll freely? If so that kinda sucks, although maybe it would make me last even longer? Meh. Have any other uncut guys delt with this issue?
