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. You can repeat this process with fresh females until he is completely wiped out.

This is called the Coolidge effect—the automatic response to novel mates. Interestingly, men ejaculate more motile sperm and they do it more quickly when they view a novel porn star. This powerful automatic response to erotic novelty is what started you down the road to getting hooked on internet porn.

Brain Studies on Porn Users

This page lists all the studies assessing the brain structure and functioning of Internet porn users. To date every study offers support for the porn addiction model. The results of these 24 studies (and upcoming studies) are consistent with 140+ Internet addiction brain studies, many of which also include internet porn use. All support the premise that internet porn use can cause addiction-related brain changes, as do recent neuroscience-based reviews of the literature:

More on Porn: Guard Your Manhood—A Response to Marty Klein

Marty Klein wrote a reaction to our original post on how porn is shaping young men’s sexual response. Klein suggested that science doesn’t empirically support our assertion of  unprecedented rates of sexual dysfunctions in young men. In fact, all studies assessing young male sexuality since 2010 report historic levels of sexual dysfunctions and startling rates of low libido. Erectile dysfunction (ED) rates range from 27 to 33 percent, while rates for low libido (hypo-sexuality) range from 16 to 37 percent. The lower ranges are taken from  studies involving teens and men 25 years old and under, while the higher ranges are from studies involving men 40 years old and under. Read more

Age 30 - Porn-induced ED cured. This really works guys. Stick to it.

Ok first of all this post is not meant to gloat or brag -well, maybe a little;D But mostly it is meant to inspire. Because, I know when I first started off, success stories inspired me a lot, and this post is meant to do just that. Background: 30 years male. Started masturbating at age of 15. From 15-18 I masturbated once a day every day. From 19 onwards averaged at least twice a day till I was 29 (to porn). There were times i even  did around 3 times a day. On the average in 7 days, I would say around 16 - 18 times.

Age 14 - NoFap has given me life again. Everything looks fucking amazing.

I see a lot of posts on NoFap about how it is a placebo, or how it is just good for extra time. While I agree other life changes plus NoFap is seriously amazing...they don't understand how much of a catalyst NoFap is for people like me. Porn left me a fucking shell of the person I used to be. I struggle with social anxiety. It got so bad that I developed a funny walk. THAT'S how uncomfortable I felt in my own body. I was fit but that didn't matter.

Age 20 - Took 11 months to beat porn-induced ED

I started this reboot when I was 19, about 11 or so months ago. Probably one of the worst cases of PIED out there, I hadn't been able to get an erection since early in high school. A little over a week ago, I lost my virginity to my incredible girlfriend and we've had sex three times since then, something I was genuinely afraid I would never be able to do. I'll post my story later, but here is my "HOW TO" post to anyone struggling.
