Wulff reports an unusual case of homosexuality, in which castration fear was not the crucial etiologic factor. Wulff interprets the homosexuality as the direct outcome of a fixation on the father. Before the patient was four years old his mother died, and his attitude to his father, though consciously hostile, was unconsciously passively sexual. His originally strong heterosexual tendencies were repressed brutally by his father, but Wulff holds that this factor, manifested when the patient was eight or nine years old, was not causal but merely accentuated the feminine identification. Wulff points out that the special structure of the individual's Oedipus situation was of more importance in the genesis of homosexuality than previous theories have supposed.
