It's called autogynephilia. Autogynephiles who have a fetish for being perceived as women are being prescribed hormones under the pretense of having gender dysphoria. Chris is one of these autogynephiles. Many of the troons featured on this forum are also autogynephiles.
This essay has more information on this topic for those interested.
TL;DR is "Autogynephilia is real, but don't cite this essay. It's trash"
The theory of autogynephilia is beyond credible. Our favorite autist goddess aside, trashy kink sites like fictionmania and the "transwomen" who follow them are perfect evidence.
This essay, however, is terrible. The ideology used by the writer is as lulzy as the stuff they quote and mock.
MtF trannies are either autogynephiliacs or gay dudes who are just SO gay that they have to transition into women? Oh, and of course any exceptions suffer from things like schizophrenia.
There are no gay or bisexual MtF trannies? None at all? Even as a minority?
Dudes banging MtFs is homosexual in nature by definition? No exceptions?
These are some pretty stupid absolutes.
Obviously no straight man is sticking his dick in a landwhale troon like Chris, but there are trannies who pass really well. Post-op, what's gonna turn a straight guy off? Some autistic spidey-sense?
The essay has a strong, reasonable subject to use as foundation, but pisses all over it.
"Talk about the elephant in the room"? Sure, but the animal your presenting seems more like a brain-damaged hippo with a hose stapled to its face. Where's the elephant?
PS. Chris is a man.
