I am uncut and can move my skin around enough for it to look like cut. Also, it covers my glans only halfway.
I had a thing when it was very painful to stretch it back, up until one day in the winter when I was 17 or 18, when I was going to college some winter morning, and I FELT my skin moving back my dick by itself, and a cold sensation on the glans suddenly. And after I came back home, I discovered that it finally fully opened, again, by itself, complete with all the dick cheese that was gathering and condensing there for 17 or 18 years.
From then on, it takes absolutely no effort to move it around. I don't even need a lotion to fap, actually.
Also, it keeps the sensitivity of the glans high, too — a lot of cut men complain about losing sensitivity so much that they actually lose any pleasure from sexual activities.
