What motivates someone to look at porn habitually?
If a such a person had an active enough conscience to think about what he is doing, he might seek a priest. Who better than a priest who has been able to renounce sexual activity for a greater good. If someone is preoccupied with sex, maybe to speak with someone who is not would be the best way for the addict to figure out how to change?
Habitual porn users have loneliness or ego issues which have tempted him to seek porn as a way out. Such solutions of course are entirely bogus. Jesus Christ is easily the answer to loneliness and correction of an ego problem will be found if someone, maybe a priest, could tell him why he was ever born, that Christ himself came to serve, not to be served.
Oh, brother. Just because you are petrified to death of your sexual urges doesn't mean sexual urges all come from Satan.
