Porn Addiction?

I'm not the type of person who thinks porn is cheating. I think it's okay. I even watch it on occasion when my bf is not in the house. But recently I'm wondering if my bf could have an addiction. We have sex a lot.... 4-5 times a week. But on the nights we don't, and I'm in bed "sleeping" I know he's on the computer watching porn. It's like the second I close my eyes I know he is on it. And from what I can tell he almost never touches himself while watching it. He'll just quickly skim through video after video. Not even really watching it. And he does the same exact thing every morning before he "wakes me up" (I'm awake with my eyes closed). He'll skim through a video for literally 5 minutes only and then wake me up for the day. I've even caught him a bunch of times quickly exing it out as I'm coming back into the room from a shower. I don't know why he feels the need to just look at it when we have such an active sex life. He doesn't even listen to it he'll just look at it and skim through a video. And what does he get from doing that for literally 2-5 minutes every morning when he's never even masturbating while doing it?
