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.

Age 19 - worst ED imaginable cured, and my life has improved in every single area

happy guyGuys. Rebooting works. Seriously, I never thought it would work for me. I was masterbating 1-3 times a day, every day, from age 11 to age 18. That's 7 years of my developmental life torn apart by porn. I had the worst ED imaginable, I'm pretty sure my penis was the equivalent of a shriveled toe. But fear not! After 339 days of rebooting, I feel like superman. My life went from being a loser, a hardcore videogame junky, barely passing classes, with losers for friends; to pure greatness.

football playerI haven't really taken the opportunity to write about my 90-day experience, however I feel like the young fapstronauts are entitled to our experience and stories. I originally joined the NoFap movement because like many of you out there I realised that I had a problem, and I needed support to help me. I didn't come here to partake in the "ultimate challenge".
