After discussing the mythological origin of hermaphrodite studies, Rollman-Branch contrasts the bisexual myth with the modern bipsychological concept, stating that the foetus begins as a female and eventually is transformed into a male. She also studies bisexual fantasies in men and women, the envy of the opposite sex, and narcissistic tendencies. Bisexual fantasies in artistic creation are presented in which the theme of bisexuality is disguised in manifold ways; for instance, through the years the voice of the eunuch, the castrated male, not only epitomized an ideal bisexual fantasy but was practiced in reality for religious purposes. Real bisexual phenomena are infrequent but the current preference for a type of voice, such as the Beatles and other groups, reflects the adolescent bisexual desires. These are manifest in long, feminine hair in the male and in the unkempt appearance (sex=dirt).
