Terrific response, Frances.

Kathryn, there is no such diagnosis. Even taking a definitional (and proper) approach broader than one of the frameworks like the DSM, Benjamin's type classification (which was intended as a diagnostic AID) is far too loose and is not in itself a classification of conditions or diagnoses. Benjamin himself said almost all patients would cross categories. And it includes aspects which are quite outdated besides.

In my opinion, about the closest you can get to something like a diagnosis from Benjamin's scale are the groups. Group one is "transvestites." Group 2 is "transsexuals, nonsurgical." Group 3 is "true transsexuals." In more modern usage, I might rename group one "cross-dressers and fetishists." (Benjamin conflates these.) Group 2 would be "gender variant." And group 3 would be "transsexual." Those original groups are the primary groups we still talk about today! If you abandon the antiquated language, it rather pops into view!
