In this paper, I, first, perform a critical, comparative appraisal of a multitude of psychoanalytic perspectives on bisexuality. Second, I discuss some of the non-psychodynamic research findings relevant to the psychoanalytic theorizing on the subject. Third, I highlight and examine a number of controversies pertinent to this theorizing. Overall, I contend that Freud's original conceptualization of bisexuality is still largely relevant today. I also argue that, among some individuals, bisexuality may represent an object-choice in its own right, while, in others, it may manifest a defense against either homosexual or heterosexual tendencies. Further, I demonstrate that both psychic bisexuality and bisexual object-choice may have determinants in both pre-Oedipal and Oedipal periods of development. I also suggest that bisexuality pertains to both splitting and integration of the mind. However, I contend that such splitting can be viewed as a useful organizing structure. Furthermore, while recognizing that psychoanalysis needs better categories than those of activity and passivity, I indicate that the splitting inherent in these categories corresponds to the intrapsychic reality that analysts generally work with in their clinical encounters with the analysands of both sexes. Additionally, I argue that no object-choice is implicitly associated with psychopathology. Therefore, I suggest that it would be beneficial to inquire into bisexuality in the non-clinical population. Finally, taking into account the post-Freudian history of pathologizing of homosexuality, I maintain that that psychoanalysts should approach both the study of bisexuality and psychotherapy of bisexual individuals in a careful and unbiased manner-in fact, much like Freud did.
