I've had both and enjoy both, but prefer uncut as long as he keeps it clean. He doesn't have to clean it every two minutes... but if he developed good habits and maintained them from an early age, then he should be clean enough to suck at any time. I've encountered a couple of uncut cocks that were not clean and I let them know right away I wasn't interested. On the other hand, I've also encountered a few uncut that didn't pass muster in the cleanliness department. It is always more enjoyable when a cock smells nice and tastes nice! A nice foreskin can be wonderful for running your tongue inside and enjoying the feel. Plus, there is docking! I am uncut and I have docked with some uncut men in the past and it is a wonderful experience.
