Brain Scan Studies on Porn Users

At this time, two studies have examined the brains of porn users:

  1. Max Planck Institute logoBrain Structure and Functional Connectivity Associated With Pornography Consumption: The Brain on Porn (2014) - A German study which found 3 significant addiction-related brain changes that correlated with the amount of porn consumed. It also found that the more porn consumed the less activity in the reward circuit, indicating desensitization, and increasing the need for greater stimulation (tolerance).
  2. Cambridge University logoCambridge University: Brain scans find porn addiction (2014). This is the first in a series of studies. It found the same brain activity as seen in drug addicts and alcoholics. It also found that porn addicts fit the accepted addiction model of wanting "it" more, but not liking "it" more. One other major finding was that 60% of subjects (average age: 25) had difficulty achieving erections/arousal with real partners, yet could achieve erections with porn.

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.

ED, anxiety & loss of libido. Now: Sex is great and I am super-confident with women

Brazilian girlIt's been 5 months now since I have watched any porn. I am getting very healthy erections even just from kissing women and it's great. I regularly chat up women on the street (daygame) and have become a lot more confident with the opposite sex.

Age 18 - More sensitivity down there, better orgasms, and I changed my life.

Age 37 - 1 year: confidence, memory, ability to communicate, anxiety, fitness and overall well being have all improved!

flirtingSo I've been doing NOFAP for over a year now with streaks ranging form a week to 79 days and in that time I have taken on a journey to become the best version of myself! I must add that when I do fap I never use porn or any visual stimulation.

I'm only on Day 5 now, but things have been getting so much better. Fapping myself to sleep every night for the past 4 years destroyed my sex drive, leaving me with ED at age 19.

London Times feature by Gary Wilson - "A cure for porn addicts who have lost that loving feeling"

Sunday Times logoYoung men are finding that addiction to hardcore videos is harming their physical ability to have real sex. Gary Wilson explains how science and online discussion groups are helping them to quit

In 2007, something strange happened on the internet. I know, something strange is always happening on the internet. But this wasn’t a viral sensation that came and went in a few weeks. Hundreds and then thousands of people, mostly male, mostly young, started questioning the effects of online pornography. On websites for body-builders, ‘pick-up artists’, medical-advice seekers, car enthusiasts, even guitarists – wherever men gathered online – conversations turned to porn and what it was doing to them.

Age 29 - cured after 5 years of PIED

Age 59 - Breakthrough: Fantasies will fade away and die as long as you don't continue "feeding" them!

Brain begins dreaming the ultimate sexual fantasy & wakes you up before it gets goodOne of my main triggers after giving up porn has been these damn fantasies, some of them would last just a few seconds, but others when my brain is "idle", like when trying to fall asleep, and often involved long detailed fantasies.
