So I'm 17 and my foreskin is really tight :/ I try to pull it back but I can't even get a third of the way, erect or flaccid. Is this normal, I'm really worried that it isn't and I have a serious problem? Inwas going to have sex with my girlfriend but the foreskin started to pull back on its own and it was really painful, so painful to the point that I couldn't do it, is there a way to sort this?
Welcome to A2A, LelouchLucifer. Yes, there is a way to sort this. What you need is to try gentle stretching of the foreskin exercises, every day. Never stretch too hard--tearing of the skin must be avoided: you just want to stimulate the skin to grow. It will take several months--it's a slow process that can't be rushed, but it will work.
