The incidence of masturbation in males and females as reported by Kinsey was cited as basic data to support Gagnon and Simon's theoretical conceptions of differences in the psychosexual development of males and females. The use of masturbation as treatment in sex therapy was reviewed. An inventory to measure negative attitudes toward masturbation was described, and four research studies supporting its construct validity was summarized. The affective-cognitive structure of masturbation-guilt was posited to inhibit masturbatory behavior and to elicit negative affects such as guilt and disgust as a consequence of masturbation.
