I think... most of my characters tend to lean on the androgynous side and it's directly related to not only my obsessive interest in 70s shoujo manga (where androgynous characters are kind of given) and also the fact I have a really androgynous presentation myself irl lmao.... But it's nice to run into others who go for similar aesthetic in terms of like looks/identification! I have a really vague definition for androgynous though because I'm aware some people use it directly as a gender identity while some consider it a presentation, and some consider it a natural physical quality but y'know I'll just mix and match.
Anyway I'm going with my trademark pretty boy since Claude deliberately prefers these kind of looks & way of behaving over more clearly masculine/feminine coded ones. It's mostly because Claude genuinely feels like that's the most natural way for him to be (he is really taking after his mother both in looks and personality) but part of it is also calculated especially with the more feminine presentation because he knows that's the easiest way to get attention in an all-boys school.
For others with a binary gender identity I have Bambi, Laurel, Knut and Lucien. As for nb characters majority of them are pretty androgynous but Amor and Morgan are probably most.
Oh yeah and obviously there is my fursona too haha
