I believe, for a long list of reasons, that families with stably married mother/father are the best way to preserve humanity and that they are most stable without wandering eyes. Avoiding having wandering eyes, or wandering loyalties, in turn, is helped when we make it easier for people to manage and direct sexual attraction to keep it within marriage, rather than otherwise. This includes avoiding porn or behaviors that are like porn to others. I want to keep my thoughts clean and faithful to my wife. I hope others can make that easier and less work, rather than often putting things in my sight that make it be more work.
