My thoughts, for what they're worth:

#1: NO, the guy watching porn doesn't mean that your sexual relationship is deficient. Sex is good for an intimate bonding experience and masturbating to porn is good for a quick and easy physical release.

#2: Porn is not "an immature way of dealing with your sexuality". The "fast food vs good food" analogy is close, but a better analogy might be a gourmet meal vs a sandwich. One's designed to be a meaningful experience that you set time aside for, and the other is a way to meet your needs in a quick and basic manner. There's nothing wrong with either approach, and both have their place in your diet.

#3: Yes, "pornography" just means "something that's designed to arouse you" and doesn't intrinsically carry connotations of objectification, degradation etc. But the majority of porn, especially the easily available stuff (I'm looking at you, Internet) is objectifying at the very least.

#4: Your brain knows that porn is fantasy. The relationship between the porn you watch and your real interactions with members of your preferred sex are about as interrelated as the last hollywood blockbuster you watched and your real life. ie. Minimally, if at all. Of course if you constantly immerse yourself in anything it'll shape your thoughts to some extent.

#5: Farryn, have you considered just asking (in a non-judgemental manner) why he watches porn? It seems to me that a lot of the problem here is that you don't know his motives and you're assuming bad ones. Everyone in this thread can speculate and generalise, but only he knows whether his use of porn reflects how he feels about your relationship. (I speculate "No", BTW).
