Im boy,19. before i used to watch porn rarely, but now ive become an addict and cant stop masturbating frequently. please help. what type of doctor should i consult? im not liking myself for doing this again after deciding not to do?

First of all you are not a boy anymore at 19yrs. Your wanting to get over the problem is half the battle won. Throw away your porn. Volunteer at a charity, do some social work, spend time with friends, play a sport or do any such activity to keep busy. if you still think you need a doctor you need to see a sex therapist. But I think you might do it on your own. Good luck
