It diminishes you as a husband and a father. 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.
