I have a pretty huge head on mine and have worn the foreskin pulled right back for many years it stays tucked behind the big head, I like the way it makes the glans even bigger and feels good but not so tight that it causes harm ... ...during an examination recently the nurse asked if I kept my foreskin like that all the time , as it might harm my penis , but I said it has been ok like that for 30 years .. so she just agreed that it would have had a good stretching in that time
