Lust is a powerful feeling that often influences our lives and relationships. Pamela C. Regan and Ellen Berscheid have written an accessible, interdisciplinary book that reviews theory and research on the characteristics of sexual desire, the individual physical and mental factors of the sexual desire, the various partner characteristics that incite sexual desire, and the association between sexual desire and interpersonal, relational events and experiences. The book concludes with an examination of the personal, interpersonal, and societal implications of sexual desire. Throughout, the authors draw on findings from their own body of research on sexual desire and romantic attraction, as well as on an extensive review of the relevant social, behavioral, and medical science literatures.
