Sex At Dawn argues that the idealization of monogamy in Western societies is essentially incompatible with human nature. The book makes a compelling case for our innately promiscuous nature by exploring the history and evolution of human sexuality, with a strong focus on our primate ancestors and the invention of agriculture. Arguing that our distorted view of sexuality ruins our health and keeps us from being happy, Sex At Dawn explains how returning to a more casual approach to sex could benefit interpersonal relationships and societies in general.
