Hi I'm a 14.5 year old male, I masturbate to much like everyday, and my penis has this wierd brown spot thing on the backside and it has like as if holes, but they seem to have happened for stretching to hard and roughness, I never used lube really and like the brown spot scares me like idk what to do or what it seems like the skin is slowly tearing, and then connected to this brown spot is a vein and it runs on the left side of my penis all the way to the top never feel pain or anything except sometimes it gets veryyyy itchy but that is fading a bit I'm gonna stop masturbating and see if that helps plz respond if very worried and idk if this is a tumor or cancer I just hope it's somethin simple like out cream on and it's gone or something. PLZ HELp ME!! Respond ASAP
