During Freud's (1920) analysis of a female adolescent he came to the conclusion that there is a constitutional biological bisexuality, a masculine and a feminine basis to our sexuality that we inherit. Freud translated masculinity into activity and femininity into passivity, which he felt did not go far enough. Following Freud's view, one's sexual identity is never entirely masculine or feminine, but would always include a mixture of two. This mixture of bisexual characteristics offers the potentiality for a complimentary masculinity and femininity. The potential for a complimentary sexual identity is actualised, that is made real, through identification with the complimentary characteristics of the Oedipal couple. This paper is a clinical study of the outcome of this process in Mr Jones. Although he was sexually involved with men and women, his father's hostility and passivity and his mother's seductive acquisitiveness finally left Mr Jones without a safe object to identify with beyond his body.
