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 23 - Porn-Induced ED gone, lost virginity, got girlfriend.

happy guy23 years old. Failed with five other women, and felt hopeless. After 17 days, I had sex, and was able to get hard on the second attempt. I also think a big part of it is that I've never felt as comfortable with a women like I do with my now girlfriend...

My skin is vibrant, my eyes are piercing and I am finally a true man. I have energy for life

happy guyI have healed considerably and my body has heavily regenerated from what was years of torture I put upon it. Porn, masturbation, drinking, drugs, and general lack of regard for health had placed me in what I thought was an unrecoverable and hopeless position.

Age 50 - Sexual Health Back On Track

happy coupleI am a fifty-year old lifetime porn user. My porn use started with the women's underwear section of the sear catalog when I was around 6 and spans the entire latter half of the 20th century. Books, magazine, online pics, erotic stories, and finally, internet video. My entire life I've had delayed ejaculation and could only cum with my hand and porn.

I actually take pleasure in doing things like sports and social activities

loversI intend to write this as perhaps a sobering assessment of what nofap has been to me. I never experienced any of the ‘superpowers’ that others did, and I didn’t really believe in them or expect them or want them. For me, nofap has been all about a return to normality.

Age 20 - Depression, OCD, ADHD going away. Stopped meds. Erections came back.

No pillsI want to share this with you guys. My name is Kyrollos and I am 20 years old. I have been a heavy user of pornography since I was 12. I used to masturbate at least once every day and some times up to 3 times a day.

The post-porn wave: why some young people are shunning videos of misogynistic sex (The Independent, UK)

laptop on a bedThere is concern in the UK over young people’s access to pornography: some want to block it, some want to see more vigilant age restrictions. Either way, the relationship that teenagers have with porn is rarely discussed with the nuance and patience it deserves. Today’s twenty-somethings are our lab rats: the first generation to go through puberty with unlimited access to online porn. The most interesting among them are those who now identify as post-porn.

Hollywood takes on porn-induced sexual dysfunctions (Movie review: "Men, Women and Children")

Jason ReitmanIn the new film Men, Women and Children, Crash director Jason Reitman, does a brilliant, excruciating job of examining the first generation to come of age on smartphones. But they aren't the only generation battered by the momentum online.

The Basics Of Rebooting

Age 17 - Zero brain fog, Social anxiety gone, Libido comes roaring back

happy coupleDays are longer than you think. NoFap taught me this more than anything else. I used to be addicted to Porn. It is hard to admit but I was. For me it was a thrice daily habit that took up 2 and a half hours on average, every single day. Over a year, that is 913 hours spent fucking myself, literally and figuratively.

"How long will my reboot take?"

Goal“I have Porn induced ED. How long will my reboot take?” This is maybe the most common question I get in emails and blog comments. And I understand why: you want to know what to expect.

While some guys with mild cases of porn-induced ED can reboot within 3-6 weeks of no PMO (no porn, masturbation, or orgasm), for others it can take up to 4 months. And in some extreme cases, it may take up to a year or more to fully recover.
