Pornography and Masturbation

Ben:  Look. Porn is getting brutal - degrading women, and sex, and even children. Surely it's vital to stop that stuff going into your mind and filling it with evil images? You'll never get them out again!

Modern porn is tremendously addictive. Some of the best brains in the world are employed to make it impossible for you to stop. You've got to escape from their clutches!

By contrast, masturbation is private, personal. Maybe it's not your masturbation that upsets God? Maybe what saddens Him is how porn and masturbation are ruining your happiness, monopolizing your mind, your time, and your nerves.

Adam:  Ha! You haven't seen the images in my mind when I masturbate. You would be horrified! I think I'm a freak. I need to give EVERYTHING up, right now!

Didn't Jesus say "He who looks lustfully on a woman has already committed adultery in his heart"? Fantasies are just as evil as actions!

Is that correct?
