The worst of sins. The history of masturbation is the one of the gravest sins imaginable, the draining of the brain and the fading of the spinal cord. It is a history of the invention of gadgets and devices to prevent both girls and boys from self-satisfaction. But none of these succeeded in eradicating masturbation, which is as seductive as it is easy to perform. A unique and felicitous illustrated hardcover book with nearly 200 arousing photographs and illustrations.
