what can I do about this?

The head of my penis is still almost fully connected to my foreskin, as you may have guessed I'm Uncircumcised. I'm nearly 15 and every time I get an erection or I want to masturbate it hurts abit because the foreskin wants to naturally retract but it can't because of the connection. I can feel the little bit of skin that connects the head and foreskin being pulled on and it causes abit of a problem. Out of what I've read, It's obvious I shouldn't have this problem as the foreskin is supposed to detach at quite a young age. Thanks for any help.
