Psychotherapy: Find a reputable psychotherapist to help explore what ISN'T happening in your relationships that induce you to masturbate.

Hey man!: At your age, you have to keep the pressure under control. Doing this also prepares you for your future as a husband and father. You should be proud of your adult man's mind and body, and you need treatment if and only if this side of yourself is taking up a huge amount of your time. Try some wholesome images rather than internet trash, and thinking about the girl you'll marry. Best wishes.
