Oof, yeah. That's a tragic one. He had dysphoria so bad he castrated himself at home and when he got the surgery he thought would solve his mental issues they botched it and gave him the archetypal stinkditch complete with bad smell and hairballs. He used to be able to get one night stands but now he's an incel. It's also worth noting that he has dysphoria about his whole body, not just his genitals. Even if the surgery was flawless he'd still be suicidal over his perceived masculine features. It sounds like he has body dysmorphic disorder on top of his dysphoria. He's what I would call "a genuine transperson" or "one of the good ones", but he got screwed by fate and will likely 41 %.

Edit: actually, it looks like the poop smell went away.

It's pretty bad, actually. It looks fine at first glance, but the big hole that looks like a vaginal opening is his urethra. The actual vagina is lower and hairier.

That being said, his neovag can't really be compared to Jazz's because this guy went through puberty and the surgeons no doubt used a different technique to carve the hole.
