The treatment of a case of female homosexuality is described and the dynamics discussed. Transvestitism was a prominent symptom. The neurotic conflict and infantile neurosis which led to the homosexuality were overdetermined. The homosexuality was a means of 1, gaining mother's love; 2, dominating mother; 3, making mother jealous; 4, masochistic submission to mother as a repetition compulsion and as a punishment for feelings of guilt; 5, defense against mother's aggression; 6, removing the rival for father's love. The author concludes that tender feelings play a minor role in at least this case of homosexuality. Hostility, and defense against anxiety and frustration, seem to be the principal motivations. Transvestitism is a symptom manifesting the need to be a man, a more obvious exhibition of masculine attitudes and behavior common among women in our culture, which is oriented and directed toward masculinity.
