The empirical study of sexual intercourse has certainly come a long way since humanity began having problems with performing the act, and Roach does a fantastic job of showing just how much work and research has been performed in the name of science on the subject of sex. In the May issue of the Journal of Sexual Medicine, “a survey of sex therapists concluded the optimal amount of time for sexual intercourse was 3 to 13 minutes.” Now Mary Roach, author of the bestselling Stiff: The Curious Lives of Human Cadavers and Spook: Science Tackles the Afterlife, has turned her scientific mind to an act that can only be performed in specific ways according to laws in certain U.S. And yet the United States is still a country that views sex as an act to be hidden behind closed doors, performed infrequently (preferably for the purpose of reproduction), and as quick and easily dispensed with. We are now eight years into the twenty-first century and the world has made many great strides in areas like medicine, anthropology, sociology, politics, and increasing our knowledge and respect for our planet and the many different peoples who live on it.
