I'm 21 and after looking at porn I realise the foreskin should be able to fully retract over the head, however mine doesn't. When i have an erection, the head is still covered. I try pulling it back slowly but i get a little bit but it seems like the top of my foreskin is too tight, or my head too big. Plus it seems to be attached underneath, not sure if thats normal or not.
Any help? Really worried
