"It was first shown in connection with the suppression of the natural sexuality of children and adolescents that there are funda­mental biologic functions of the human animal that have nothing to do with the economic distribution of the classes and that class boundaries overlap and cut across one another. The suppression of sexuality relates not only to all strata and classes of every patriarchal society; it is precisely in the ruling classes that this suppression is often most pronounced. Indeed, sex-economy was able to show that a large part of the sadism made use of by the ruling class to suppress and exploit other classes is to be ascribed chiefly to the sadism that stems from suppressed sexuality."
