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.

All addictions hijack the same core neurocircuitry, which runs on the same neurochemicals (even though each addiction also involves additional neural circuits and neurochemicals that differ between addictions).

YBOP review of "The New Naked" by urologist Harry Fisch, MD

Eminent urologist Harry Fisch, MD has performed a much needed service by saying some things that need to be said about missing pieces in today's naive understanding of human sexuality. For example, he addresses the adverse effects of excessive internet porn use on men's sexual function and expectations, as well as the adverse effects of too much sex toy use in women. He also advises people who need help to get it from therapists who actually understand sexual addiction. (Many sexologists still deny its existence!)

Age 24 - Day 86: Seriously life-changing.

friendly guyI've been watching hardcore porn consistently since I was 18 years old, and [looking back] was truly addicted from 19-24 [now]. That's 5 years of my life, wasted on watching some people on a screen have sex with each other in all sorts of weird ways - that I now look at objectively and see to be a pretty weird fetish.

Age 20 - I wasn't confident, lacked social skills, really self conscious. All of that has changed.

flirtingWhile I'd never be able to lay out all of the knowledge and experiences I've acquired over the last 180 days, I'm going to give you my biggest breakthroughs.

Age 29 - The Monster in The Closet

Hi to all NoFappers, this is not going to be the usual sharing of experience. There is enough information on what happens when you watch porn and how it feels when you try to cease that practice. In short my story with porn is about 13 years old (29 years of age at the moment) 2 years of which had been spent in fighting with it.
