Myth 1: Psychoanalysis is all about sex.
This is probably the most common myth about psychoanalysis, probably stemming from Freud's Three Essays on the Theory of Sexuality, where he addressed the question of infantile sexuality, sexual "perversions" and the question of the "sexual instinct" in neurosis. However, psychoanalysis is more about the individual human experience and the workings of the unconscious than it is about sex per se. Sexuality plays a major role in the human experience but it is certainly not the only aspect of the human mind of interest to psychoanalysts.
Myth 2: Psychoanalysis never ends.
Although it is true that psychoanalysis takes longer than most psychotherapy approaches, termination and ending is an important part of the psychoanalytic process and often, the most enriching part. The reason why psychoanalysis requires time is because it aims at a deep understanding of oneself and a significant change in healing, which can only be achieved over time in a safe, trusting and honest relationship to oneself in the presence of another.
Myth 3: Psychoanalysts require that you lay on the couch.
