Attraction to transwomen is called gynandromorphophilia. But there are at least two forms, in males: autogynephilic and non-autogynephilic. To simplify, I call gynandromorphophiles ‘GAMPs’. Autogynephilic ones I call ‘AGP GAMPs’ and the others ‘non-AGP GAMPS’.
I used to think that non-AGP GAMPs were actually bisexual, but they do not always conform to the standard understanding of bisexualism. In the first place, using the Western definitions, non-AGP GAMPs are never attracted to masculinity and will avoid partners who display it. The southeast Asian definition depends on the act played in sex, and bisexuals in this case are happy both to penetrate and to be penetrated. But those GAMP men who do desire to be penetrated seem to be predominantly AGP.
As far as I know, no work has been done that might clarify this, so, until it is, I will use the definitions as above. The AGP-GAMP profile is quite clear and well understood, but there may be unanswered questions regarding the non-AGP profile. It might split into two types, although most non-AGP GAMPs appear not to desire to be penetrated.
In the West, since the 1960s, homosexuality has been defined by attraction. Gay men are attracted to masculine sexual features—muscular taught bodies, facial hair, prominent jaws, assertive attitude and so on. If we define homosexuality in this way, then it should be clear that being attracted to soft bouncy hair, full breasts, red lips, big eyes and so on simply cannot be seen as a homosexual attraction, for a man.
If it were as simple as that, then that would be it. But it’s not. There are some other issues to deal with, especially where the woman retains a penis. I’ve made a YouTube video discussing this, here.
