I'm uncut.
I was using the bathmate two or three times a week, but usually only manage one now.
The head of my cock is usually not covered by the foreskin anyway, so it's not so much an issue for me. I tend to notice when my glans is covered by the skin ( e.g. if I find it that way when I take a pee ) but occasionally that does happen.
I can't imagine the skin on mine staying in place, inside a bathmate in use. It retracts if I start to get hard, or big for reasons of warmth or any other reason ...
