As I illustrated in my last post it’s really all about gender disphoria. That being said, the origin of said disphoria is not yet understood.
My suspicion is that it is rooted in biology and something happens to the fetus which creates this predisposition to desire to be the other sex; whether its exposure to pesticides, endocrine disrupting chemicals or other sources is not yet known.
Its pervasive nature, so powerful and so immune to eradication by the individual strongly suggests a biological core.
As we have seen in the studies and interviews with post operative transsexuals, there is eroticism preoperatively to the idea of feminization present in both types and both have high degrees of satisfaction with their adopted gender once transition is determined to be the course of action. If the disphoria is potent enough, the only recourse appears to be hormone therapy and GRS which will effectively cure the conflict between mind and body and lead to much improved life quality.
The differences in behaviour seen in both types of MtF transsexuals, is often explainable by their sexual orientation. Homosexual disphorics are more likely to transition earlier due to an early acceptance of their effeminate nature and their sexual attraction to their own sex; given a choice between being a woman and a disphoric homosexual male, it’s really no contest.
Heterosexual disphorics are far more likely to ignore their feelings and try and conform to expectation. Given that they are attracted to the opposite sex and desperately want to be “normal” in order to be acceptable to their female partners as well as to society, they will do their utmost to suppress their gender confusion and simply assimilate the best way they can. Holding their breath leads to the invariable explosion typically after the age of 40.
Gender disphoria seems to have a severity scale which often determines whether someone will transition or not. Harry Benjamin even alluded to it when he began to classify his patients into types, ostensibly measuring the severity of their affiliation with the other gender; his type IV being essentially caught in the middle and being the most conflicted.
Ray Blanchard proposed that non homosexual disphorics have a paraphilia and homosexual disphorics are simply gay men but this model is simplistic and does not go towards a root cause for the gender confusion which is present.
Why would a homosexual male seek reassignment surgery to romantically and sexually attract males and, conversely, why would a heterosexual male be sexually aroused by having a female body?
Blanchard’s typology suggests distinctions between MtF transsexuals, but does not speculate on the causes of transsexualism and in fact criticism of the research and theory has come from John Bancroft, Jaimie Veale, Larry Nuttbrock, Charles Allen Moser, Julia Serano, and others who say that the theory is poorly representative of trans women and reduces gender identity to a matter of attraction.
Another huge mistake of Blanchard has been ignoring FtM transsexualism which even further erodes his work. He has failed to explain why women want to become men and in fact there are a significant number that indeed do transition; if not in the same numbers that we see in MtFs.
