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 14 - I was an overweight, weird, dull, boring kid that plays video games & faps all day.

young guyAs of today I'm 92 days in on nofap and have decided that I will never masturbate again as I have show myself I can't handle it without spiraling down the dark road to PMO land.

Age 31 - My mojo came back. Social, personal and professional life back to normal.

 NZ mountainsIt's 51 days for me, and I'll be honest. Some days I don't even think about PMOing, and other days I'm really tempted but find myself saying 'No' much easier.

Why Shouldn’t Johnny Watch Porn If He Likes?

Sexual brain training matters—especially during adolescence

Monkey faceIt's normal for kids to want to learn all about sex, especially during puberty and adolescence when reproduction becomes the brain's top priority. For this we can thank the specifics of teen-brain development.

Think of an adolescent jungle primate watching another band with such fascination that he (or she, in some species) leaves his companions, and endures the slings and arrows of being without allies at the bottom of another troop's pecking order—all for a chance to get it on with exotic hotties in the future. The things our genes do to guarantee genetic diversity!

Now, fast-forward to a young guy discovering the mind-boggling novelty of Internet erotica:

Age 27 - ED: 10 years without sex - now 7 months of daily sex without issues

happy coupleI've been a member of the site since March or April 2013 and it has been a big help to me. I did post an initial success story when I first started having sex again in April 2014 but I can now confirm I'm well and truly rebooted.

Age 27 - Cured PIED & delayed ejaculation, despite crippling OCD

young guyIt's been a while since I've been here and I'm thrilled to say I'm cured of DE and PIED. Abstinence from porn has cured both my anxiety and inability to orgasm and now I'm in what I hope is my perfect relationship.

Age 13 - Less social anxiety & procrastination, Renewed confidence, Erection is like steal

young guyIt all started when I was 11, a friend of mine told me about fapping and how to do it. I tried and I'll admit it felt good. I started watching porn a few months before it. I mostly played meet n fuck because my internet was slow and those videos would never load. I'd kill to play a meet n fuck game at that time.

Age 27 - Clinically depressed: I wake up and I'm not depressed, I have goals and hope again!

questioning doctorBeen on this challenge since march this year! I have gone through multiple attempts ranging from 4-5 days to 10-12 days with my max at 19 days 1-2 times! I've been into pmo since 13 years old...but my bad habit escalated after 18 years old when I had my own pc in my room.
