If you want to resist watching porn and you can't, that makes it pretty bad.

Porn has been shown to decrease libido, and lower testosterone.

It alters the way you view relationships becauae of how realistic it is, and your brain can't tell it's just a movie your watching or real life.

You unconsciously pick up on these bizarre body languages which is 80% of communication, and it causes women to view you differently because your giving off body language that isn't actually yours.

I work at a mental hospital, every single youth here (18 or below) has one thing in common, they all viewed porn regularly at a young age. Every single one of them.

I think it's a lot worse for you than we know.

I recommend /r/NoFap for countless accounts of how people's lives were changed when they stopped watching porn. My life included in that list. Literally every aspect of life improved when I began practicing semen retention. And I only watched porn 3 or 4 times a week before that.
