How do I stop masturbating and get rid of ographic mental images?

Do not answer my question with a question. Do not tell me it is normal. I am a addict. Addictions are not healthy. I masturbate probably 3-4 times a week, but still consider myself addicted to masturbating and . It is all impulsive. I feel no less than an animal acting on urges. I want to be a man, not an animal. I want to have self-control. I do not want to be a slave. Usually, I masturbate after work when it is really late. I need to stop, because if I don't I will never be able to stay faithful to my future wife. How to break the addiction?
