What shapes our sexuality? Is it a product of our genes, or of society, culture, and politics? How have concepts of sexuality and sexual norms changed over time? How have feminist theories, religion, and HIV/AIDS affected our attitudes to sex? Focusing on the social, political, and psychological aspects of sexuality, this Very Short Introduction examines these questions and many more, exploring what shapes our sexuality, and how our attitudes to sex have in turn shaped the wider world. Revealing how our assumptions about what is ´normal´ in sexuality have, in reality, varied widely across time and place, this book tackles the major topics and controversies that still confront us when issues of sex and sexuality are discussed: from sex education, HIV\AIDS, and eugenics, to religious doctrine, gay rights, and feminism.
