Here is an interesting video demonstrating the science behind this dangerous addiction. I would also add William Struthers “Wired for Intimacy. How Pornography hijacks the male brain” as a remarkable look at the psychological affects of porn on males. As always, no Christian man should keep this addiction from secret. There is no healing in secrecy.
The second video details a porn experiment. It illustrates the nature of porn addiction and how it produces the same affects as other addictions.
