Just read the book, pretty concise overview of the nature of the problem, and the steps towards the solution.
There was one claim that I found peculiar - not that I'm disputing it, just saying that it's very thought-provoking.
On page 4 of Sexual Healing, Benjamin Brice writes -
"Heroin also damages the receptors in the brain. However, when you damage your receptors with pornography, it is 800% slower to recover and repair the brain. That's how powerful it is, it has a longer withdrawal and healing power than heroin!"
Although I don't doubt his claim, I'd be interested in reading up on more info regarding pornography being 8x more damaging to dopamine receptors than heroin.
