i had this experience when i was 16... what i did was trying to stretch it everyday (as my dad and uncles advices), and some time let my extremely sensitive glan stayed out in my pants all day... which some day made me pee with blood, yeah!! pain as hell man... and it took around a week to get it healed!!

it took me around 9 months or more to open it wide enough to have my mushroom head out when hard and some other few years of brushing my extremely sensitive glan in my pants (sometimes in my boxer brief, never in bikinis as the 2 huge nuts were too sweaty) to fade that fucking pain as the first day out..

now i leave the glan out all the time as the tight foreskin never that tight again... i tried to cover it back all the time but the mushroom head never stay in there again.. the only pinkish eye wanna see the world, i think ;)

so please keep trying... it's not that pain as an operation, i think... i'm on your side, man.. it's never too late, mate.
