The paper begins with a history of personal and psychotherapeutic attitudes and approaches to the various kinds of homosexuality, male and female, from Freud's in 1905 to those of psychiatrists and psychoanalysts writing at the present time. The author discusses, with clinical illustrations, the many ways in which patients with latent or overt homosexuality may present to the psychotherapist and the complex challenge they pose. He stresses the heterogeneity of the condition, and shows how the analyst may be of help, whether or not there is desire for change of orientation.
