So he's a straight autistic dude starved of female interaction to the point that anytime one is friendly to him, they are considered a romantic prospect. Can't understand a female perspective, or anyone else's.
The outlet has to then be porn. Fixated on how easy it is for a female to get romantic interest, where he is envious and desires how easy it is for woman. So then troons out. That was easy, but is now confused why he isn't getting all that romantic interest from cis women. Afterall, he's a woman, it should be so easy for them as their objects of desire.
