ISBN 0-253-34171-X "Thus the institutionalized recognition of the queer-identified, or homosexual, transsexual, is historically groundbreaking. Rosario scrutinized how transgenderism has been described in relation to homosexuality and heterosexuality in both the revised third edition and the fourth edition of the [DSM]. In the DSM-III-R, the classification of "transsexualism" was divided into "homosexual" and "heterosexual" subtypes. However, sexual orientation was based on one's birth sex, so that an FTM who was attracted to women would be deemed a female homosexual transsexual, whereas an FTM attracted to men would be considered a female heterosexual transsexual. These diagnoses were especially confusing since a female homosexual transsexual – that is, an FTM who desires women – would actually identify himself as a heterosexual trans man. And an FTM who desires men, a female heterosexual transsexual, would self-identify as either a gay man or a queer-identified FTM."
