There is substantial research in porn addiction, some psychologists even define "stages" of this addiction. It may be included in future psychiatric disorder manuals: http://en.wikipedia.org/wiki/Pornography_addiction http://en.wikipedia.org/wiki/Pornography_addiction However it seems like addiction is reinforced by the negative social attitudes towards sex (i want what is forbidden/taboo), which is really a vicious cycle. Rationally speaking, porn shouldn't even exist (a dog never has to pay for it).
