Porn, like anything, is bad for you in excess but most people don't do it in excess. As long as you control your own impulses and not blame anything/anyone else for your problems (the jews, the blacks, the left, women), you can achieve anything you want to in life.

Porn addiction beyond the above, is not a real concept. Anyone who tries to push that onto you and treats it like a sickness is a grifter, likely for God.
