Hi, From your history, it looks like what started as a normal growing up behavior has become a frustrating and psychological preoccupation. The good thing is that you have realised your problem and more than willing to control it. You could yourself think of doing dome productive activity whenever thoughts of masturbation come to your mind. Please remember that masturbation itself is a normal adult self pleasurable behavior. But when you can t stop yourself and it starts affecting your daily routine, it becomes an addiction. You could also try some mind relaxation exercises. Please consult a psychiatrist if you are unable to control excessive masturbation. With normal frequency of masturbation at your age, married life and quality of sperm are not affected. Hope this helps.
