Matt, I salute you for the courage to write this under your real name, and thank you for sharing your experience.

> The difference between internet porn and porn from the past is just the abundance of new material that there is. (...) At the basic level, it really is not much different from any other addiction. Old, offline porn is different in that it gets stale pretty quickly. There are only so many times you can look at a magazine or video without it getting boring.

I think this is the key point (and dopamine-related discussions only distract from it). I also came to the realization that the big part of the problem is the same thing that keeps many addicted to Hacker News or Reddit - it's that whenever you look, there's always fresh new content, so it never gets boring.
