This article describes a previously unreported pattern of atypical masturbatory behavior, which presents as either an erectile or orgasmic disorder in men. Four case histories are described of men who masturbated in an idiosyncratic manner. The distinguishing features of the masturbatory style include a prone position and daily masturbation over a period of years. It is suggested that the primary care physician or specialist (urologist or neurologist) screen for this problematic style when presented with male sexual dysfunction. Further, and more controversially, it is suggested that a primary prevention model would argue for masturbatory instruction in the home, classroom, or pediatric clinical setting.
