More of a research book on culture and quasi-medical, than a book having to do with sex; having very little to do if at all, with the intimacies of love between two people nor procreation. The information within these pages cannot be understated. Keep an open mind. It is far more than just some random listings of perverted sex acts; Complete with history and background; some of which have become today's customs we take for granted. Did you know; the tradition of carrying your bride over the threshold originated from the sex practice of bondage? Insight into the true nature of a people. ( )

This is the most thorough accounting of all human sex practices that I have found so far. Short on words and long on substance it beats out sex encyclopedias that are twice its size. I don't know if I would say that it covers every conceivable sex practice but it comes very close. Well worth the read if you're looking to expand your knowledge of sex beyond different positions. ( )
