Warning - massive spoilers, stay out of this thread if you haven’t played the game.
Me, I’ve actually only seen one ending so far. I badly need to get Suzushiro’s ending to check if anything along what I’m about to discuss is covered, although I doubt it. I also haven’t quite managed to read ALL of the general PW thread, but I’ve seen enough comments from different angles that I wanted to raise a thread specifically for discussing sex and gender.
Namely - Is Chris a boy or a girl?
Physically, it’s obvious what set of equipment she’s got.
Mentally, he makes it clear that he does not have any secret traditionally-feminine personality hidden underneath his princely persona. He is not in disguise. Chris is Chris and always has been.
Emotionally/sexually, it’s extremely unclear. E does kiss Suzushiro (and dammit, I really wish there’d been a CG for that), although eir mind is more on Arata at the time. E is fighting in the waltz to become a ‘real’ boy, and then presumably to marry a girl and have babies with her. E does have sex with Arata, but appears highly conflicted about it.
It’s not just fear of being weak that makes Chris reject a female persona, because there are plenty of ass-kicking princesses in this game. Chris simply isn’t a princess.
As a bisexual with an interest in genderqueers none of this is a problem for me, and I even wish the game had played more with the ambiguity. This may be an issue of translation, but once Arata finds out he exclusively refers to Chris in his narration with female pronouns, even when talking to people who don’t know, and never seems to worry about slipping up. Or about whether the female pronoun is the correct one. And yet Chris is masculine enough that it caused problems for some players, and Arata doesn’t seem to struggle with the attraction in the way that the players do - the conflicting thoughts of Chris-girl in his bed and Chris-guybuddy at his side, or to deal with what would have happened if there had been no plot twist and Chris had won the Waltz and become a physical boy.
There’s also the issue of how Suzushiro feels about her boyfriend turning out to be physically female. I haven’t done her path, but she appears to be still devoted to Chris. What are her expectations of a future there? Do her feelings change at all, or is a prince in a girl’s body still a prince?
Then there’s the matter of Demon Dude possessing a body which is technically female, and I don’t think that was brought up at all… No one referred to HIM with female pronouns even though the body he was in was female.
(Plotwise, if they’d expanded things a bit, I would have liked there to be an option to back off and stay Best Buddies after the initial accidental sex (which I would have rewritten because it was an awful scene) and to be able from there to progress to proper romance with the other princesses, but hey, can’t have everything.)
So - is a girl a boy if he acts bishonen enough, despite the body? Is a boy a girl if she dresses the part? Is it “gay” for a guy to have sex with a girl who acts like a guy?
(I tend to fall into ‘your gender is what you say it is’ so if Chris says he’s a boy, he’s a boy. But then, I don’t CARE if someone’s a boy or a girl, so my opinion on the matter is different from some of you players out there…)
If this subject is too touchy for a full discussion here I’ll take it off to wacky feminist blogs. 
Do try to be polite for the GLBT readers!
