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.

"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.

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.

Age 20 - No more PIED, Feel like a man first time in my life

happy guyNo more PIED, that's why I started. Feel like a man first time in my life. Understand "pride" and keeping your word. No longer a little bitch.

Age 30 - Finally came! Delayed Ejaculation fixed. Thanks NoFap

couple kissingSo it finally happened. I (30M) came during PIV last night. After 47 days of not looking at porn and 32 days without MO, I was able to do something I wasn't sure would ever happen. DE was my whole reason for doing NoFap.

Age 19 - So much more confidence, more energy, less depressed, girls are prettier

happy guySo 50 days ago I started my biggest Nofap streak to this day. Some good things that I noticed from Nofap:

Age 27 - (ED): My sex life became amazing, but I overdid it.

couple kissingI went through several flatlines along the way - but man, it only gets better. Seriously does. My self control has gotten pretty good.

Age 16 - I had quit sports, quit hobbies, and stuck to 24/7 call of duty after school

16-year oldWell, after a long journey of hardmode nofap here is the info I owe. Profile: 16 years old, Junior in High School, want to be something when I'm older, just don't know exactly what yet.

"Boys and Porn: A Moving Target" (Huffington Post)

kid watching computerTherapists can be a little confusing when it comes to assessing porn's risks. Some would have us believe that only teens with inherent vulnerabilities become addicted, even though addiction research that shows that early exposure to supernormal stimulation, alone, increases the risk of addiction. In search of another point of view, I interviewed author Gary Wilson, who has a lot to say about the unique risks of today's Internet pornography in his new book, Your Brain on Porn: Internet Pornography and the Emerging Science of Addiction.

Thoughts of suicide and depression lower if not nonexistent

starfish in wavesWhen you fap to porn, your motivation is drained and you feel bad about yourself. You are victim to watching someone else fuck the girl of your dreams. A girl you would give anything to spend one night with. When you think about it, it is extremely depressing.
