Overt behavior. Freud himself discussed a constitutional predisposition to bisexuality. As he originally used the term, it applied to mental life generally and all men had the potential to be bisexuals. However, he was skeptical of the existence of bisexuality and noted that proof rested in biological experimentation. This did not hamper his followers and the term has been so broadly used, according to Rado,28 that it is almost meaningless. Any relationship between two men, any dominance or submissiveness, competition or friendly cooperation is a manifestation of homosexuality perhaps only in unconscious or latent form. Any "femininity" defined as psychoanalytically labeled "sex symbols" in fantasy, dreams or in manifest culturally stereotyped female behavior represents latent homosexuality whether it is ever orgasmic or not.
