Push-Pull

Not unreasonable at all for you to feel that way, but this is one of those topics that boil down to communication. After getting some insight here, you should chat with him about how you feel.

As a guy, I could see where 'most' guys will, ahem, take care of themselves regardless of having a willing partner. The amount will vary of course, but unless the partner is actually dehydrating the guy through too much sex, I would not be surprised for any guy to take matters into his own hands on occasion. I think it's how the guy equalizes the sex between him and her; it allows him the frequency he may desire and something different without having to cheat. The porn is just another way for a guy to achieve that.

The short version is that unless there are other signs of larger problems, I wouldn't read too much into it.

As an aside, you now have an awesome opportunity to kick your love life up a notch. You mentioned being open to new things, so if you feel comfortable, you could ask him to show you his favorite porn bit and if it's not objectionable, mimic it for him.
