I regret masturbating and i want to stop, how?

Some people elect: not to masturbate for spiritual or religious reasons. In those circumstances - maintaining focus on their doctrine can be of help.

Find real love: Most people enjoy their bodies by themselves, and finds this helps them stay focused and prepares them for adult life. In fact, most young men can't even get to sleep after a few days of total abstinence. If someone's told you it's 'wrong' or 'unhealthy', get some wiser counsel. Cherish your sexuality and look forward to the day that you'll share it with one special, wonderful person.
