I think men should avoid porn in general because it's bad for the brain. It desensitizes you to normal sexual stimuli, and constantly masturbating reduces libido and energy levels for men. I don't think that's controversial though.

Where I think you guys might disagree with me is that I would go one step farther into the extreme and say that masturbating to porn is akin to cheating if you already have a partner.

I get that men are different. We have a penchant for more sexual release and more novel sexual experiences compared to women but that doesn't mean that our standards for relationships should drop. Save of all of that energy for her. If she's the right one, she wants it from you.

What really brought this point home to me was this youtube video below. If you're in love, you're constantly thinking of what that person is doing at that moment. Your partner can be thinking warm thoughts of you, and meanwhile you're in your room touching yourself to videos of another woman. It feels disgusting and disrespectful when you think of it like that.
