Here are this person’s plight and experience. They have this brain imbalance as a teen. They don’t know it. They find porn and masturbation. The chemical release of an orgasm makes them feel balanced, better, or able to sleep. They found a medicine for their brain problem. Then wham! They become Pavlov’s porn dog and the medicine becomes the addiction. The addiction becomes the problem.
