http://www.youtube.com/watch?v=VOMtXa3vScY I recommend it. It is 40 minutes long, features an example of an porn addict (if you thought your addiction is bad, check out this guy), they scan the brains of the porn addicts and it shows clearly what effects it has on the different parts of the brain.
TRIGGER WARNING! All I did was hover over the link and the thumbnail alone is a massive trigger warning. It's a BBC special, and Britain isn't shy about showing breasts. Be careful...
yeh there's actually footage of porn, but w blurred faces in this. also all the suggested related/videos on the side are pretty provocative. watchout.
