like awhile ago i wanted to get rid of some sensitivity on my penis head (im uncut) cuz it would take hours to cum during sexb/c my head was to sesitive so i had to go slow so now i lost alot of it by doin a trick i didnt apply and cream or anything on it, i would just pull back the foreskin and leave it in that position all day finally i noticed the skin on my head started to peel like as if i had sun burn now i think i have lost to much sensitivity . here the question can i get back the sensitivity by just leave the forskin over my head for awhile?
