Here is a short piece from the book.
The Clitoris is pure in purpose. It is the only organ in the body designed purely for pleasure. The clitoris is simply a bundle of nerves: 8,000 nerve endings to be precise. That's a higher concentration of nerve fibres than is found anywhere else in the body, including the fingertips, lips and the tongue...and it is twice...twice....twice the number in the penis. Who needs a handgun when you've got a semi automatic?
