You are unconcerned about relationship skills that build a mutually fulfilling life. Your wife has value to you only to the extent your wife gratifies you. You become increasingly selfish in your perspectives and outlooks. It perverts a powerful gift from God into a destructive evil. Pornography never makes a man more godly.
Pornography never makes a man kinder, more compassionate, more understanding.
Pornography never makes a man more like Jesus. Pornography never makes a man a better Christian, a better husband, a better father, or a better person. It robs the man's children. It robs them of the depth and quality of love they should experience. It robs them of the role models they need in the healthy, loving interaction of Mom and Dad.
