'In this fine book Toates gives a lively tour of the psychology behind 'how sexual desire works'. As a pioneer in motivation theory himself, Toates is an ideal guide into how incentive motivation processes work to produce sexual desires. Beyond psychology, he leads the reader on forays into neuroscience, and includes many excellent quotations as case samples, all to help put the psychology of human sexual desire into better perspective. This is a highly readable and illuminating book.' Kent Berridge, University of Michigan
