Hi, I'm 14 and ever since I was young I have never been able to pull my foreskin back whatsoever, it's as if the end of the foreskin is kind of glued together. I can't even see the head of the penis when I try to pull back, the foreskin just kind of stretches. There is no pain and no peeing issues. I was wondering I feel this was anything to be worried about and what I should do about it so I can pull it back. Help would be appreciated, thanks!
