-Reddit isn't "scientific" enough for you? Fine. The scientific literature says the same thing. [Blanchard 1985](/papers/blanchard-typology_of_mtf_transsexualism.pdf): 73% of non-exclusively-androphilic transsexuals acknowledged some history of erotic cross-dressing. (Unfortunately, a lot of the classic studies specifically asked about cross-_dressing_, but the underlying desire isn't about clothes.) [Lawrence 2005](/papers/lawrence-sexuality_before_and_after_mtf_srs.pdf): of trans women who had female partners before sexual reassignment surgery, 90% reported a history of autogynephilic arousal. [Smith _et al._ 2005](/papers/smith_et_al-transsexual_subtypes_clinical_and_theoretical_significance.pdf): 64% of non-homosexual MtFs (excluding the "missing" and "N/A" responses) reported arousal while cross-dressing during adolescence. (A lot of the classic literature says "non-homosexual", which is with respect to natal sex; the idea is that self-identified bisexuals are still in the late-onset taxon.) [Nuttbrock _et al._ 2011](/papers/nuttbrock_et_al-a_further_assessment.pdf): lifetime prevalence of transvestic fetishism among non-homosexual MtFs was 69%. (For a more detailed literature review, see [Kay Brown's blog](https://sillyolme.wordpress.com/faq-on-the-science/) or the first two chapters of [Anne Lawrence's _Men Trapped in Men's Bodies: Narratives of Autogynephilic Transsexualism_](https://surveyanon.files.wordpress.com/2017/07/men-trapped-in-mens-bodies_book.pdf).)
