Although there has been much discussion about things like the causes, loss, and maintenance of sexual desire, there has been little research into the nature of sexual desire itself. Consequently, most of the discussions on these topics have gone on without any clear idea about what it is that is being discussed. Readers will be interested that at last there is a full-length book that attempts to say what sexual desire is. Further, this book takes an interdisciplinary and intercultural approach, drawing on a wide range of texts and research. Drawing on such diverse sources as psychology, philosophy, and biology, a thorough discussion of sexual desire is presented. Also presented are new accounts of the sexual process, gender, romantic love, and love’s relation to sexual desire.
