However, this is not always the case. When the sexual goal deviates from normality, it is called reversal. Inversion is essentially homosexuality, although within it there are three subdivisions: absolute, amphigenic and occasional, which vary in exclusivity and emotional connection with the inverted sexual object. According to the cultural norms of Freud's time, inversion was considered innate and/or degenerate. However, Freud does not agree with this normative distinction. In degeneration the entire being of a person is affected; this is not the case with inversion. Second, if inversion were innate, there would be no room for variation in sexual behavior. However, as discussed by Freud, there are subdivisions of inversion, each with different sexual roles and goals. For example, in classical inversion, men wish to play the role of a woman. This behavior has been observed in sexual inverts, but is certainly not universal
