Honestly, if it was me, I'd just think that he's intersex.
Even if your partner never backed down on the second gender thing and once a month smelled like alcohol and got really seemingly uncontrollably horny?
Sounds like biology
I feel like the very first sign is the fact that he excretes from his ass and the fact that he got pregnant... from his ass. Intersex genitalia don't work like that dude
The seme's and seemingly the rest of the world is just dense asf and refuse to betray their already established logic regardless of the mountains of evidence to the contrary. They analyzed his blood, at the very beginning, he's a male, biologically and still got pregnant and psychologically sane.
crying over how they still don’t believe him even when he can literally get pregnant, smells like alcohol at random times and gets high fever whenever he’s in heat, AND the hospital camera should have showed that he just disappeared out of nowhere like dawg what more do you want
