I Bet you any amount of money that the
Penis Bible is a ripoff of this book called <a href="http://www.amazon.com/gp/product/159800168X?ie=UTF8&tag=direlife-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=159800168X">Scientifically Guaranteed Male Multiple Orgasms and Ultimate Sex</a><img src="http://www.assoc-amazon.com/e/ir?t=direlife-20&l=as2&o=1&a=159800168X" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" /> by Alan Ritz!

The book talks about the same biochemisties and bringing yourself back to puberty state and supplements just as I said.
He also talks about a muscle he calls The VIP Muscles. Its located between the anus and tail bone. You can read a little bit more on locating the muscle at
Ehealth Forum
So my recommendations don't waste your money on the penisbible. Take a trip to barnes and noble. Study the book, take its advice. And if his advice works out, buy the book and support the author.
I think I have happily located the VIP Muscle. And I must say I enjoy working it better than the PC Muscle.
My trick for locating it is to the extend your penis upward then contract the VIP Muscle, if you get No tug, then I think you have correctly located it. If your penis tugs, then you Have Not located it but the pc muscle rather.
I am definitely going to give the VIP Muscle a shot because to be honest I never received much good from the PC Muscle anyway.
