Are Narcissistic Homosexuality in males and Autogynephilia linked? I argue that they are.
Many have tried to negate the relationship between gender-dysphoric transition desire, and homosexuality. In one category, of course, this is futile. Homosexual Transsexuals (or true Transsexuals) are born with an innate condition called Sexual Inversion, which is the result of hormone-delivery anomalies in utero. This, being a biological effect, displays variation in intensity. So an aetiology is formed, with Transgender Homosexuals (feminine male and masculine female) at one end, and full Transsexuals (MtF and FtM) at the other. The precise point at which an individual sits depends on many factors; but they are on a relational scale of expressions of the same underlying phenomenon: innate Sexual Inversion. These individuals have normal levels of narcissism, in line with natal men and women.
Narcissism per se is not a disorder, rather a normal and useful trait; but in excess it causes Narcissistic Personality Disorders or NPDs. NPDs may be innate.
Nobody argues that Sexual Inversion is the cause of all homosexuality or transition desire; same-sex attraction and cross-sex identification can be symptoms of several underlying phenomena and it is not always easy to tease one from the other. But the Sexual Inversion phenomenon and the Transgender Homosexuality/Homosexual Transsexualism aetiology are easy to establish and identify. What about the other forms, though?
