It should be mentioned as a caveat that Blanchard's a sloppy soft-scientist, and Bailey's even worse.  Leaving aside all the ethical violations and outright "I made the story up" content in The Man Who Would Be Queen (I've read it, and it's a crap book which unlike actual science-for-the-layman books like Altemeyer's The Authoritarians, has no citations whatsoever), Bailey was the Northwest University professor responsible for the "Fucksaw Incident." While Blanchard's papers on transsexualism are "I'll ignore data that doesn't fit my elaborate model," gynandromorphophilia does exist--but even then, there's the caveat that Blanchard doesn't distinguish between "I like futa porn with nice tits" and "I like flat-chested effeminate male crossdressers," a distinction PornHub, Xhamster, and every other profitable porn sites makes (there's a reason Kitsy Ladrando's porn is in the Gay category and Andreia Albertini videos aren't); this is despite that being the one area where Blanchard's "homosexual"/"nonhomosexual" dichotomy would actually be useful.  Blanchard, Rosenthal and Bailey's study showed that GAMP men:   Had a high arousal response to female stimuli and low response to male stimuli, just like the heterosexual control sample and the exact opposite of the homosexual control sample   Had a high response to females-with-dicks ("gynandromorphs" in the paper), unlike the homosexual and heterosexual control samples   While bisexual men were not included as a sample in the study, other studies (in particular, Rosenthal's 2013 study showed that bisexual males have high arousal to both male and female stimuli   Taken together, these findings logically imply that bisexuals have a low arousal response to MtF stimuli and therefore "bisexual" is too inaccurate to be a useful umbrella term for "I like guys, I chicks with vaginas and I like chicks with dicks."  In other words, "I'm attracted to transgender people as well" is a useful categorization, since a subject who has high arousal to M stimuli, FtM stimuli, F stimuli and MtF stimuli would be a valid usage of "pansexual."  Tumblr isn't.  study only male subjects?  That's the problem with Blanchard.  He uses special pleading to argue that "being aroused at the idea of being a woman in a sex scene" is exclusive to men and "typical of male sexuality," romance novels be damned.  Never mind that Amy Bloom, author "Conservative Men in Conservative Dresses," mentioned in the very same article in which she lambasts crossdressers (apparenlty wymyn are saints who can do no wrong and wearing women's clothing is only okay when gay men do it) that she was aroused by the ritual of pulling on stockings:  ...though I know that there is an erotic dimension to getting dressed up (it's not just cross-dressers who appreciate the silkiness of a slip, the slide of a stocking) Don Kulick  I bought a Scribd account just to read Kulick's Travestis cheaply because it's so expensive to access otherwise--but there's nothing in the book that isn't at least alluded to in the documentary Boys from Brazil.  Source: I read the book cover-to-cover and watched the full documentary. Unlike Kulick, Boys From Brazil doesn't take a heterogeneous setup and tell us it's homogeneous.  In Boys from Brazil, some travestis feel 100% like a woman inside and want SRS, others don't and just want the appearance and body of a woman--and Gaspar, a feminine gay man and a non-travesti crossdresser, says he doesn't want the breasts and face of a woman (very similar to the femboy subculture among gay furries).  Contrary to claims about the "trans lobby," Gaspar gets no pressure to transition or take hormones despite being close friends with travestis and having an economic incentive to do it.  Kulick takes the same milieu as Boys from Brazil and claims all travestis just consider themselves viados, "faggots," low-prenatal-testosterone not-a-Real-Man males, and that travestis think anyone who wants SRS and thinks they're a real woman trapped in a man's body is crazy.   Never mind that Roberta Close, who changed her ID documents to "female" and had sex-reassignment surgery before moving to Europe with her husband, was a travesti. Granted, Kulick's a lot smarter than Mema's House author Annicka Prieur.  But Vek Lewis points out he has the same problem as Prieur of wasting book space on academic sperging about "gender is constructed" and omits useful information (in Prieur's case, to the point that she hardly tells readers about Mema Ortega's biography and activism--there are only passing references to it, such as when Mema visits his heterosexual married friend and fellow gay-rights activist Miguel to invite Miguel's family to his birthday party.  Prieur saw fit to omit Mema's and Miguel's activism entirely to tell us about how goshdarn oppressive and unfeminist it is that the jotas try to look and be traditionally feminine--the kind of guidance /r/FeminineBoys over-intellectualizers would greatly benefit from).  Prieur also makes sure to tell us that Mexican jotas adopting a feminine appearance and being flamboyant is "reinforcing gender norms"--Prieur's much happier with Norwegian gays who dress and act like heterosexuals. Kulick claims all travestis want a masculine boyfriend, a straight man who exclusively penetrates and thereby alleviates dysphoria.    In reality, a nonzero percentage of travestis have gynandromorphophilic taste in men.  In Kulick's book, Treze's marido was a crossdresser who worked the streets with her.  Outside of Kulick's book, Tranny Fag star Linn da Quebrada penned the line "Boy, if you want to get with me, you'll have to get faggier," and da Quebrada's co-performer Jup do Bairro expressed the same preference for girly men in makeup in an Instagram post. Meanwhile, a far more universal preference than "I want a masculine real man" in the book that Kulick barely talks about is preference for young, neotenous males--boyzhinos get sex for free, the starting age for paid maridos is 15 with the oldest age being 30, and Keila specifically chose Tiane as her marido because he looked 19 at the age of 30.    Kulick's relevance to the gynandromorphophilia study is that the travestis classified the clients who exclusively penetrated as "men" and the clients who wanted to be penetrated as "faggots."  This perfectly maps onto whether or not GAMP men considered themselves straight in Blanchard's study.  Blanchard's Americans agreed 100% with Kulick's Brazilians that a man who only wants to penetrate trans women have a more masculine brain than men who have an autogynephilia fetish and want to penetrated by a trans woman's dick.
