In this article I explore the concept of a postoedipal adult sexuality and its role in the erotic transference-countertransference processes seen in psychoanalytic treatment. This concept challenges the fundamental assumption that, whenever erotic feelings enter the psychoanalytic space, the analyst always stands in the role of the oedipal parent. It suggests that clinical choices made from within an oedipal model often fail to recognize certain significant developmental changes. An extended clinical example is provided.
