Hi i am experiencing serious desensitization of my penis area when masturbating it's been like this for months is there anything i can do to regain my sensitivity or a drug i should take or have i masturbated beyonv repair or is a pipe damaged helpme?

At you age, I doubt that the desensitization you experience is cause for concern. Do you reach ejaculation through masturbation? Have you experienced sexual intercourse? If so, is the sensitivity noticed? I think that your technique, perhaps the lubricant you are using, is part of the problem. If so, attempt masturbation without lubrication. If this doesn't help, see a trusted doctor.
