Freud: “Three Contributions to the Sexual Theory,” p. 29. Translation by Brill. “In a non-sexual ‘impulse’ originating from impulses of motor sources we can distinguish a contribution from a stimulus-receiving organ, such as the skin, mucous membrane, and sensory organs. This we shall here designate as an erogenous zone; it is that organ the stimulus of which bestows on the impulse the sexual character.”
