This explains what's behind the idea and typology, and defines the two different types of trans male ('trans woman'):
In 1985, sexologist Ray Blanchard used a larger sample size and confirmed the observation that there exists a fundamental difference between homosexual transsexuals (homosexual males romantically and sexually attracted to males) and non-homosexual transsexuals (which includes heterosexual, bisexual and asexual transsexuals):
This study tested a prediction derived from the hypothesis that asexual and bisexual transsexualism are actually subtypes of heterosexual transsexualism… (a) cluster analysis of their scores divided the subjects into four groups: heterosexual, homosexual, bisexual, and asexual… there were no differences among the asexual, bisexual, and heterosexual transsexuals, and all three groups included a much higher proportion of fetishistic cases than the homosexual group… these findings support the view that male transsexuals may be divided into two basic types: heterosexual and homosexual. (Blanchard 1985)
Together, these papers teach us that transsexuals may be grouped into homosexual and non-homosexual transsexuals, and that the latter group appears to contain a number of subtypes which could be taken to correspond to an ordinal degree of fetishistic transvestisism. These observations are supported by empirical evidence; the difference is manifest in “a much higher proportion of fetishistic cases than the homosexual group” and so Blanchard confirms the identification of two types of male transsexual, who are differentiated by sexual orientation, with one group displaying a fetishistic, or paraphilic history.
Blanchard became a key figure in the history of investigation into transsexualism a few years later where he attempted to impart some meaning and rigor into the terminology surrounding the taxonomy of transsexuals, as part of systematic study into this phenomena, he coined the term “autogynephilia” as a clearer description of something that had hitherto been described as part of automonosexualism. This is what has become known as “Blanchard’s transsexual typology” or the “two-type transsexual typography” (Blanchard 1989):
Gender identity disturbance in males is always accompanied by one of two erotic anomalies. All gender dysphoric males who are not sexually oriented toward men are instead sexually oriented toward the thought or image of themselves as women. The latter erotic (or amatory) propensity is, of course, the phenomenon labeled by Hirschfeld as automonosexualism. Because of the inconsistent history of this term, however, and its nondescriptive derivation, the writer would prefer to replace it with the term autogynephilia (“love of oneself as a woman”).
It should be noted that the use of the expression “erotic anomalies” is used in a morally neutral context, to describe sexual acts that are inherently non-procreative, rather than being a pejorative expression.
Key to the concept of autogynephilia is that it’s not something that is always on the mind, nor is it something that is confined solely to cross-dressing:
It should be noted that the concept of autogynephilia does not imply that autogynephilic males are always sexually aroused by the thought of themselves as women, or by dressing in women’s clothes, or by contemplating themselves cross-dressed in the mirror – any more than a man in love always obtains an erection at the sight of his sweetheart, or pair-bonded geese copulate continuously. Autogynephilia, according to this hypothesis, may be manifested in a variety of ways, and fetishistic cross-dressing is only one of them. Those individuals labeled transvestites by contemporary clinicians would, on this view, be understood as autogynephiles whose only -or most prominent -symptom is sexual arousal in association with cross-dressing, and who have not (or not yet) become gender dysphoric. (Blanchard 1989)
The fact that the group "women" contains representatives of all social classes does not necessarily mean there's no point to recognising women as a distinct group who have been collectively subjected to an astonishing degree of oppression for millenia. That's the whole point of feminism isn't it? Or at least of radical feminism.
