An early sex manual in the 1960's. Written by "J", it became a national best seller as it was the first "how to" manual on sex written by, and for, women. The books central thesis was that by employing good sexual technique, a woman of modest apperance could captivate any man. It was also published at a time when practical instruction on having good sex was almost unprecedented. The book seems very innocent by modern standards, but it was one of the first to mention oral sex, and sold in the millions. It led someone called "M" (probably a ghost writer) to write a companion for men, titled The Sensuous Man. Which also sold very well. The book is lighthearted, and comes into print often enough that copies are readily available.
