Abstract
Considering its whole theory is based on sexuality, it is surprising that there is little discussion in psychoanalytic literature on strap-on, which indeed meets the need for sexual function. If strap-on had not been somehow disregarded, its ability to turn into/turn something into a prosthesis could have been easily recognized as a form of psychosexual function. Beyond compensating for the lack of a limb, it has earned a chaotic place especially in psychosexual function; exposing it in detail can enable us to see the importance of the idea of the prosthesis in psychoanalytic theory and practice. Apart from its concrete function, we can think of a prosthesis as a phallus image in the psychosexual process; or as the skill to make it functional as a genital organ. The concept of “Strap-on Mother,” in other words, disregarding the phallic image in the oral symbiotic period, was developed through Freud’s Schreber case. It was thought that the theorists acquired ‘symbiosis reverence’ as a defense while reading psychoanalytic texts. This can be likened to the analyst’s disregarding of the neurotic root of the demand for maternal care which comes about during therapy. Based on the concept of the prosthesis, this article focuses on the chaotic function of sexuality and the issue of the determination of gender.
