How do you stop lusting?

The old expression applies here, "Idle hands are the devil's workshop". Find something that you enjoy doing that does NOT lead you to temptation.

Someone who is trying to lose weight does not hang out at a bakery or pour over cookbooks (or food websites). Similarly, someone who is trying to avoid lust should not indulge in pursuits that trigger their weakness. If you find this difficult or impossible to do, then you must reevaluate the sincerity of your desire to stop. Your success is directly related to your commitment to change.
