How often have you been naked in the locker room when another guy comments on your foreskin? It has happened to me several times. Some guys will open by saying "I see you're not cut." and it will go from there. A few times I have been asked "how does it work" and I have demonstrated how I retract the foreskin. Once I made this demonstration for three other guys in the sauna. I have found that many guys who are cut are fascinated by those of us who are not.
