How can women tell their man not to watch porn or masturbate and it be okay and not considered controlling?

So many women tell their man to not masturbate. How is this considered not controlling? If a man were to tell a woman that everyone would say he was abusive and controlling (most people probably would anyway). I’ve seen this double standard on this app alone.

It seems to be a pretty normal thing to tell your man not to masturbate. I don’t understand how people justify this to themselves and tell themselves it’s not removing body autonomy? You see people say “well what works for your relationship etc etc” but HOW is this not seen as super controlling and weird? You are telling your SO what they can do with their body. It’s weird to me and I genuinely don’t understand it.

This obviously doesn’t include addiction.
