"Gender Identity Disorder" was a term created in the DSM-III in regard to transsexuals, and the categories were "GID/Children Transsexualism"; "GID/Adolescent and Adult, Non-transsexual type" and "GID/Not Otherwise Specified".
In the DSM-III, the terms "Homosexual", "Heterosexual", and "Asexual" were used - with quite a bit of confusion [REF].
