I want to say straight out that this book is not for everyone. There are those who will be offended by reading the flap on the front cover. But then there are people like me who just can’t help but read a book that puts a humorous spin on the science of sex. Roach gives a history of the study of intercourse from the ancient greeks to current times. Instead of being erotic, her text will have you rolling with laughter at the mistaken perceptions of the past and at her own embarrassing adventures researching the field. She tells of Leonardo Da Vinci’s unenthusiastic investigation of the nether regions of the bodies of executed criminals and some of the inside stories of famous researchers such as Kinsey, Masters, and Johnson. This book is a joy to read for those with a curiosity of science and humanity or if you just need a good laugh.
