I am an 18 year old male and I am concerned about a particular problem involving the foreskin of my penis. It doesn’t retract it’s stuck on the head of the penis, if I try to pull it back it will hurt. The tip of my penis is sometimes red. Other than that I experience no pain or discomfort, but it has affected my sex life. I’m not sure if this is a serious condition, but I’ve read online that the foreskin usually retracts on its own which I hope is still the case, though I am already 18.
