autogynephilia is a made up word for a made up "disorder". ray blanchard made up this word and this "disorder". to quote the TSRoadmap site
"Autogynephilia" is a sex-fueled mental illness made up by Ray Blanchard. Blanchard defines it as "a man’s paraphilic tendency to be sexually aroused by the thought or image of himself as a woman."
paraphilia is a particular technical term, in psychology. it means that it involves a) nonhuman objects, b) the suffering and humiliation of ones self or ones partner, or c) children or nonconsenting persons.
if you are saying that a person transitioned, or that a person is trans, so they could have new toys to play with? that's transphobic. it's not funny. cut it the fuck out. if you're going to continue to say it and/or continue to think it's funny, please let me know whether you're saying a) that a trans woman is actually still a man, b) that they or their body parts are non-human objects, c) whether you think they're humiliating themselves or their partner, d) who precisely is nonconsenting, or e) some or all of the above so that i can be clear on in exactly what way you're an asshole.
