yes my foreskin and mainly the shaft skin has much more room to slide up and down along the length of my erection. I can move the skin about 2 inches up and 2 inches down; when flaccid I can pull the skin down completely over my glans and sometimes it just stays there unless I retract it. Lots of jelqs over the years and probably stretching too; also pumping has done this to me I’m sure its helped.
I also wear a ManHood that is a glans restoration sleeve and have worn one pretty much 24 hours a day since August 2021. My glans is like a pool cue now, always pink or reddish in color (not gray or lifeless looking at all), always warm and not cold, it gets harder and fuller/plumper when I get erect, and my glans reflects light in almost any setting even dark rooms if there is any kind of light in the room I can see it on my glans. Because the sleeve covers part of the penis too it helps the foreskin between glans and circ scar get rejuvenated and it is extremely more sensitive now and the pleasure and stimulation I feel in my penis now is up like over 100% from before I started wearing the sleeve. The sleeve also keeps my shaft skin a little moist well not wet but not dry and its softer now too like crazy soft, so it probably helps the suppleness of the skin and if I tried to make my skin even looser to do more foreskin restoration (I quit PE early this year completely, I had to for my wife she has complications with sex due to menopause and thyroid issues) I’m sure my foreskin would be even looser.
