Don Juanism or Don Juan syndrome is a non-clinical term for the desire, in a man, to have sex with many different female partners. The name derives from the Don Juan of opera and fiction. The term satyriasis is sometimes used as a synonym for Don Juanism. The term has also been referred to as the male equivalent of nymphomania in women. Historian Carol Groneman has claimed that these terms no longer apply with any accuracy as psychological or legal categories of psychological disorder.
Psychiatrist Carl Jung believed that Don Juanism was an unconscious desire of a man to seek his mother in every woman he encountered. However, he didn't see the trait as entirely negative; Jung felt that positive aspects of Don Juanism included heroism, perseverance and strength of will. Jung argues that related to the mother-complex "are homosexuality and Don Juanism, and sometimes also impotence. In homosexuality, the son's entire heterosexuality is tied to the mother in an unconscious form; in Don Juanism, he unconsciously seeks his mother in every woman he meets....Because of the difference in sex, a son's mother-complex does not appear in pure form. This is the reason why in every masculine mother-complex, side by side with the mother archetype, a significant role is played by the image of the man's sexual counterpart, the anima."
One of Theodore Millon's five narcissist variations is the amorous narcissist which includes histrionic features. According to Millon, the Don Juan or Casanova of our times is erotic and exhibitionistic.
Sigmund Freud explored the connections between mother-fixation and a long series of love-attachments in the first of his articles on the 'Psychology of Love'; while Otto Rank published an article on the Don Juan gestalt in 1922.Otto Fenichel saw Don Juanism as linked to the quest for narcissistic supply, and for proof of achievement (as seen in the number of conquests). He also described what he called the 'Don Juans of Achievement' – people compelled to flee from one achievement to another in an unconscious but never ending quest to overcome an unconscious sense of guiltSándor Ferenczi stressed the fear of punishment (Hell) in the syndrome, linking it to the Oedipus complex.
