ABSTRACT
One of the reasons for the relegation of sexuality to a secondary position in clinical treatment—it would be better to say in the various treatments, to do justice to their diversity—is the ever-increasing interest aroused by patients presenting non-neurotic structures. If the primal scene is at the centre of Sigmund Freud’s concerns here, then sexuality in general remains very much an issue in his elaborations, especially where they are centred on anal eroticism. Interpretations propagated themselves, from Melanie Klein to many others since then, and one can note that the accent placed on the part played by sexuality in the case has varied considerably among the writers. As for the French writers who are interested in borderline cases, whether Bergeret, McDougall or they maintain an important place for sexuality in their work. Sexuality and the ego would be less in opposition to one another than in a complementary relationship.
