Psychoanalysis is less interested in organised, genital sexuality than in the anarchic, repressed, unconscious sexuality. It asks about infantile sexuality in adults. Kai Rugenstein discusses, based on Sigmund Freud and Jean Laplanche, the guiding principles of an intersubjectively oriented drive theory and its implications for psychoanalytic practice. It becomes clear how, beyond mere talk about sexuality, analyzes are about finding a way of interpreting that mobilizes the dynamics of the unconscious sexual in the transference and thus revives blocked development opportunities in patients. Special attention should therefore be given to working with and in transference love.
