Porn and long distance

Hi all I was advised to post on here to ask for some help regarding my relationship and porn. My boyfriend( 22) and I (22) have been together for 2 years. We have had a wonderful relationship and we both love each other very much. However, in the beginning of the relationship we both decided it was okay for each of us to watch porn. I hadn’t watched porn in the past but I gave it a try. What that meant was we watched it daily once or twice a day sometimes even more. Personally I still had a high sex drive, but it began to affect my boyfriends. He’d still have sex with me but he’d still watch at least once a day. I wasn’t sure if that was addiction or not. One day he said he had jerked off twice so couldn’t have sex. I was devastated. It wasn’t until then that I asked myself why I was watching it so frequently instead of having sex with my bf. We’ve talked about it quite a bit and he agreed he might have an issue and suggested he can try and stop. He admitted it would be difficult to completely give it up. I thought I was being insensitive and suggested we’d only watch it together. However we don’t see each other frequently and idk if it’s fair for me to ask him not to watch when I can’t be around to have sex. Is it unreasonable for me to ask to not watch porn if he needs to masturbate? I know the appeal of porn as I’ve watched and I do have a high sex drive but I can’t help but feel like it doesn’t bring any good into a relationship. In other words can porn be used when in a relationship in a healthy manner ? Thanks In advance for the help !
