“Porn addiction” isn’t even a thing. Look in the DSM-5. At most it’s a compulsion you let take over your life. It’s usually a term religious people use when they get caught doing something others disapprove of. If you actually see this as a problem, every time you just have to yank your winkie, go touch grass. Seriously. Go sit in your front yard. I’ll bet that removes the temptation quite quickly. And, if not, the cops will eventually get you some help.
