I like having a foreskin yeah, i've always felt a little sorry for guys who didnt have the choice to keep theirs. I dont agree with circumcition unless its medically nessacary.
I have a comfy, loose skin. Its warm, moist and soft and stops your glans touching anything os i think it keeps uncut guys more sensative than our cut fellow man.
Mine doesnt retract by itself, its too loose and long but then when it rolling over your glans it feel cool, plus it traps any pre keeping it all kinda moist.
Plus if you pinch the end closed when you pee, it balloons out and look really funny, lol. Im also a fan of docking (another mans glans under your own foreskin) and im looking forward to giving that a go one day.
On the down side, if you go for days and i mean 'days' without pulling it back to clean your glans in the shower it can have a bit of a minging scent to it and a little smegma, something i dont think cut guys have to worry about because your glans are always in contact with your underware.
