There is a debate whether or not porn is really that bad for you. I think in moderation it is okay. Just stay away from the beastiality! What is considered addiction? It is natural to masturbate/have sex. Humans are animals. What about for people that can't get or don't want/have a boyfriend/girlfriend for whatever reason or aren't getting enough attention from their significant other? It is a form of stress release that most men use and not surprisingly quite a few women. It is much better than a prostitute or cheating on someone. The biggest problem I see is most guy's wives won't compare to a porn star, so what's the point in getting married? This is why feminists are against it because they have lost sexual power over men. Don't want to have sex with me because you're mad at me? I'll find someone on pornhub. However, there is nothing like the real thing, especially those latinas. I digress.
If you really want to quit, you can put an adult filter on your computer, quit masturbating altogether, use your imagination (that can get weird too), take a vacation to Thailand, or find yourself a girlfriend (or two) with a ravenous libido

Good luck!
