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.

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 23 - (ED): A guy and his girlfriend both describe reboot, 130 days

young coupleI have read tons and tons of success stories here and I was always bothered (no offense to those) because 90% were about people who had no (real) PIED and 'just' felt like their focus or mood or whatever improved after giving up porn.
