How can a guy stop masturbating?

Marriage, maybe: All single men do this and most continue at least occasionally into married life. It's basically a good thing -- it keeps you focused, it's fun and safe, you learn about your mind and body in preparation for being a grown-up, and only ideologues have problems with it. I'm going to assume you do not have an obsession with erotica that interferes with other important things. Talked with dad? Cheers.
