So two days ago i woke up and everything was fine with my penis but later in the afternoon i noticed my penis red sticking to the glands (I was able to pull it back) and really sensitive to water and movements. Yesterday it was a lot better but the foreskin just seems to crumple around the tip of my head i can retract it a bit but not as much as before I'm 16, and i can't maintain an erection now before i could easily so please anyone help me out here

Thanks Chance
