coming at this from the opposite direction, i'm uncut but have a pretty tight foreskin. when i'm completely flacid it hangs over the end but as soon as I get a semi it's starting to roll back and by the time it's rock hard, it's pulled back tight and, I guess, looks pretty much like a cut dick. I imagine there are cut guys with loser skin than me.
In fact my foreskin has a lot of trouble accommodating my girth, I have a bunch of tiny scars around it from different times when it split over the years. My cock is at it's widest a couple of inches behind the head and this is exactly where the loose skin that hangs over the end of my cock stretches back to when i'm fucking a woman.
I think these scars have reduced sensitivity and contributed to the fact I find it hard to cum but at least they haven't got any worse for 15 years. I guess my foreskin eventually got used to it.
