Is my thinking unrealistic?

Is my thinking that men are out there who don’t watch porn unrealistic? I’ve been battling for a year now with my boyfriend watching porn, he is so perfect in every other way, it hurts that the man I could see myself marrying is doing something I can’t see my future husband doing. I have voiced my boundary over porn plenty times so I’m not looking for advice on how to talk to him about it, I’m fighting a fight in my head with myself on maybe I am the one being unrealistic? That all men watch porn ?

I’d like someone to join this battle in my head haha and either make me feel better about my boundary or give me the smack of truth.
