OMG at least the guys could fuck him in the ass this poor girl now has to go down on an open wound which has poor hygiene.
I have a feeling that nothing is happening sexually between them, or if it is, he's occasionally going down on his GF and there's nothing reciprocal.
The arrested sexual development in boys given puberty blockers early on not only means that their genitals don't fully develop, and thus don't provide enough usable tissue to create a manhole (as happened here, as well as with Jazz Jennings), but they also never experience sexual arousal or desire, which naturally occurs from the onset of puberty. The surgical rearrangement of their genitals doesn't help either, given that numbness, reduced sensation, or pain are common even in post-op adult troons.
Adult troons whose puberty was blocked are basically sexless. One who is a public figure or entertainer may keep up a pretense that they have normal levels of desire and great sex lives, but they don't.
So it's no surprise to me that a trooned-out gay boy whose only sexual function is to receive anal or provide oral, and derives little, if any, pleasure from it, would beard up with a woman who makes no sexual demands on him—because the kinds of men who would willingly have sex with a boy castrated and mutilated as a child into an inadequate simulacra of a girl, and who gets no pleasure from sex, never has, and never will, are
that fucking awful.
