The Addiction.

My favorite conversation to walk in on with new couples is when the girlfriend asks her newly acquired boyfriend if he has ever watched porn. The conversation typically goes like this:

Scene: Couple is watching Comedy Central (some stand up special) and a Girls Gone Wild commercial comes on.

Girl: "I hate these commercials."
Commercial: "Are you ready to see these young college girls bare it all..."
Guy: "Me too. It's annoying."
Commercial: "Girls Gone Wild WOOOO!"
Girl: "If I asked you a question, would you answer it honestly?"
Commercial: "As an added bonus..."
Guy: "Yeah? Why wouldn't I?"
Commercial: "You'll also receive Girls Gone Wild..."
Girl: "Alright then, have you ever watched porn?"
Commercial: "Call now, and receive free shipping!"
Guy: "No, maybe like once or twice but that's it." <<< He's LYING!!!!
Girl: "I was just curious."

Scene: Penis enhancement commercial starts.

End Scene.

Of course he has watched porn dummy! More than at least 30 times! No guy would ever admit watching porn, or even having masturbated to it! It's just not gonna happen.

Every guy has gone through a porn phase. I'm sure there was a specific genre he liked as well. Using my friends and I as examples: Asian, Latina, Large Breasted, and Blondes. It's just the plain ugly truth.

Questions you may want answered:

Is watching porn kind of sad? Yes.
Are we ashamed of admitting it? Yes.
We do like it? Yes.
Do we watch it everyday? Some, not all of us.
Can we break the habit? Most scientists believe it could be possible.
Am I watching porn right now as I'm writing this? No.
Would I if I wasn't writing this? No, I don't have the time.
Why do we enjoy porn? We're horny ALL THE TIME!

How can a guy keep his mind distracted from the urge to watch porn? Well, he can take up a hobby. I for instance enjoy learning about cars, researching stocks, and reading up on current events. Please note that a girlfriend could also qualify as a hobby.

If you don't want your guy to watch that "filth" I would suggest that you have sex with him on a daily basis. I really don't see another way around it. Failure to do so will drive him back to the problem... it's like dealing with a drug addict.
