If there is any addiction that is almost completely misunderstood and virtually denied on all levels it is compulsive masturbation. It is socially acceptable and even encouraged for people to admit other addictions like alcohol, drugs, eating, work, fetishes, promiscuity, phone sex, etc. But the person addicted to masturbation is shunned. Masturbation is just another form of sex. Don't worry about it.
Most people discover masturbation in puberty.
Some don't discover it until their early adulthood. The defenders of masturbation propose advice that is as foolish as the attacks against masturbation. The defenders of masturbation refuse to admit that masturbation can become an addiction. The profession in most denial about the addictive aspects of masturbation is psychotherapy. You don't have a problem.
