Hey, when i was 16 (now i'm 17) i discovered that i had to pull back my foreskin, after a few weeks of excercise i could get it all the way back when i was really flacid. (only like 3 centimetres).
When erect it doesnt work, and i don't have the same fast progress at all. Didn't get any further after that year of trying...

that concerns me.

but even more at the moment that it the foreskin is all tight again the next day. every time i go sleep with a loose foreskin and then it's all tight again the next morning, and it takes hours to get it back over the head when flacid...

Help plz
