Autogynephilia isn't a thing, please don't confuse euphoria bones with that idea. It's more like they're so happy that their body gets confused and every reward circuit starts firing.
Honestly, both of those sound equally nonsense to me.
But either way, consider this.
Nekotoufu made this spin-off, where both chapters come dangerously(?) close to autogynephilia. He made chapter 76, which insists that "a penis doesn't belong in yuri". He made multiple chapters where Mahiro gets aggressively horny whenever he has his comrade, and it's even worse when that happens to Momiji. He made what could become a perfectly good "trans girl coming out" story, yet he refuses to commit to that narrative in any way that wouldn't require a lot of selective perception.
He's not your ally. He's not your enemy either, but he doesn't share your western sensibilities.
Why do you expect him to write his characters according to your specific values, rather than by the tropes embraced in anime?
