Martha Cornog promises to give us information on masturbation usually only accessible to experts of sexuality or ethics, philosophy or religion. In six sections she covers a lot of information, all of it well documented and much of it in the words of the scholars, authors, and thinkers she's used in her research. This isn't a how-to book, it isn't erotic or porn, and it isn't for the casually curious. It is a well-written and supported look into the often taboo subject of self or mutual pleasure for pleasure's sake.
