How much porn is too much porn?

***THIS QUESTION IS FOR THE LADIES THAT ARE NOT AGAINST PORN ONLY***
I already know how you ladies that are against-porn think and I respect that opinion.. But I'd like for you to keep your insights regarding my issue ... With that being said... 
I don't mind my boyfriend watching porn at all. I understand they need to have a quick release or maybe the mood strikes when I'm not around .. Or whatever .. However.. I feel like my man's porn habits are that of a single guy that doesn't get laid. We have sex at least 5 times a week. My boyfriend needs a lot of recovery time in between climaxing.. So we usually only do it once a day. I thought maybe he just had a low sex drive compared to my super high drive. But as it turns out , I found out that he gets off alone most days.. And that's why we only have sex only once.. Is this normal ? Watching porn almost everyday or every other day? Would it bother you??
