“I don’t care if my SO masturbates, but no porn”

Do you agree with the statement above? Is it unreasonable?

I would never take my boyfriends natural rights and instincts away by telling him he isn’t allowed to masturbate, not only is it controlling but it’s kinda ridiculous. However, porn is a no for us. We both agreed that we don’t need it or desire it. But it was my idea to bring up to him that porn makes me uncomfortable, something about the idea of my boyfriend jacking off to other people upsets me. I think if he needs a visual he can look at my photos or videos or ask me for whatever he wants. That’s where we are with it. I just want to know if any other ladies agree with this statement. Also I just have to say I’m not looking forward to the over confident women that are going to come and bash me for my feelings, forcing them upon me. If you’re ok with it, good for you. But to the others who aren’t, please share your experiences and stories about how you and your SO have approached it.
