This is coming from someone who made it half a year on no-fap (and no sex) in the past. Porn is not too different than any other vice, and is being used to cover up or mask other problems in your life. You can beat porn by replacing it with another vice (mine was video games), but at the end of the day, the problem doesn't go away. If you're lonely, depressed, fat, ugly, have a shitty job, no future, no purpose etc. then the temptation to go back to porn will always be there. You need to work on fixing yourself and your life situation. This can be difficult if you're married and your sexual outlets are limited to just your wife. And while we're on the subject, no, getting a girlfriend or married does not fix the problem.
