The Science of Pornography Addiction

Of all the new innovations that came with digital technology, one of the greatest–and some argue, one of the most dangerous–is Internet pornography. 

Never before in human existence could someone literally pull up an endless supply of graphic sexual images. Like a drug, regular pornography viewing can dull the sexual senses and tolerance, and can even trigger guilt and withdrawal syndromes. 

Asap SCIENCE even argues that long term use can even have very permanent effects on the growth of the brain, especially at a young age. The topic is discussed further in The Science of Pornography Addiction.
