Came across this book recently.
Haven't been able to give it a read but it's on my radar. Have you read it or come across it?
Many books exist on this subject. This one is #1 on amazon.

Here are the classic symptoms of an addiction to sex/porn:
Escalation. Over time the use increases or moves toward more aggressive types of sex/pornography.
Persisting in the face of consequences. If the user loses jobs, relationships, health, legal status or has other consequences in their life but persists in the habit.
Repeated failed attempts to quit.
There is a lot of brain research that is opening up our understanding of what is happening in the brain when we have sex (with others or with ourselves). Basically, our perception of the world narrows as we build to orgasm. When we orgasm there are chemicals that are released that cause us to bond with who we are with or what we are thinking of. Once is not as much as a big deal but done over and over it adds up to issues. For a good, well balanced book with lots of neuroscience on what porn does to the brain then check out Wired for Intimacy on Amazon.
Also understand what is going on in the head of a persistent porn user. In porn the user is the center of attention. The universe revolves around them. The people in porn play out their wishes, never question them and give them exactly what they want. The people usually look unrealistic instead of real. The actors/actresses in porn are gone when the act is over so there is no real relationship - no arguments over the dirty dishes, etc. This is VERY unrealistic.
Porn is terrible for the people producing it. The myth is that these actors/actresses are doing what they are doing on their own free will. While some may be a great majority are in a sense "forced" into what they do by bad decisions and desperate situations. Some are even outright forced using violence. How do we know which kind of porn we are consuming?
At best using porn is like taking a burning log out of the fireplace and taking it to bed with us. The warmth may feel good for a while but sooner or later it will burn us and lead to destruction.
Also, there was a TedTalk on the use of ED medications and pornography - as in pornography is driving the growth of ED medications. They have some pretty good info on how removing pron from ones life tends to remove the need for ED meds.
