Cambridge Study: Internet porn addiction mirrors drug addiction

Cambridge University logoComments: The long-awaited Voon study highlighted in the UK documentary "Porn on the Brain" is finally out. As expected, Cambridge University researchers found that compulsive porn users react to porn cues in the same way that drug addicts react to drug cues. But there's more.

Compulsive porn users craved porn (greater wanting), but did not have higher sexual desire (liking) than controls. This finding aligns perfectly with the current model of addiction, and refutes the  theory that "higher sexual desire" causes compulsive porn use. Drug addicts are thought to be driven to seek their drug because they want – rather than enjoy – it. This abnormal process is known as incentive motivation. This is a hallmark of addiction disorders.

The other major finding (not reported in the media) was that over 50% of subjects (average age: 25) had difficulty achieving erections with real partners, yet could achieve erections with porn.

Finally, researchers found that younger subjects had enhanced reward circuit activity when exposed to porn cues. Higher dopamine spikes and greater reward sensitivity are major factors in adolescents being more vulnerable to addiction and sexual conditioning.

The results of the Cambridge study, and last month's German study (Brain Structure and Functional Connectivity Associated With Pornography Consumption: The Brain on Porn. 2014), provide very strong support for hypotheses put forth here on YBOP from its inception in 2011.

What happens when you drop a male rat into a cage with a receptive female rat? First, you see a frenzy of copulation. Then, progressively, the male tires of that particular female. Even if she wants more, he has had enough. However, replace the original female with a fresh one, and the male immediately revives and gallantly struggles to fertilize her.

Woman - had a PMO Problem, Husband joined me in no PMO, Experience Is Interesting

couple in bedI joined this site a couple of weeks ago because I had gotten to the point where I was staying up all night, every night, looking for porn to find something that would get me off, allowing me to fall asleep. Usually I'd spend 3-4 hours of looking for the "right" porn or erotica, but sometimes that would extend to 5-6 hours sessions if I didn't feel satisfied with the orgasm, and go looking for a second.

Supernormal Stimuli: This Is Your Brain on Porn, Junk Food, and the Internet (Huff)

Barbie and junk food"A wise man rules his passions; a fool obeys them."

Given the rapid pace of technological change, one has to wonder whether or not our brains (and bodies) have been able to keep up with all the new stimulation that is available.

Age 19 - I was watching 10 tabs at a time of hardcore fetish by age 13. I could barely get hard by age 14.

NZNofap works. Period. I cannot believe how much progress I have made looking back at my journal. I used to watch porn 3-4 times a day from age 11 to age 18. That's 7 years of my developmental life that was completely tarnished by porn.

couple in bed So last night after not being able to have sex for 2+ years, I had sex 3 times with a beautiful girl with absolutely no signs of PIED.
