When either flacid or erect I cant pull my foreskin back, when I pull it back I can stretch it just so you can see the tip but no more I dont know what to do
If you're under 16 or so this is NORMAL.
Stretch your foreskin. The more times you do it each day the faster you'll get results.
Either pull down on the shaft skin when you have an erection, it'll stretch the head OR use your fingers and spread the opening.
How does your advice change for older people with this issue buddy? (E.G 22) Cheers x
