My clan has a lot of dragons that are probably bisexual, pansexual, asexual, demisexual, or graysexual. But since it's also a chaotic Arcane clan filled with weirdos, a lot them wouldn't really bother with self-identifying, and most just go with the flow. Not all of them though, and a few of the ones that haven't thought about get honorable mention too.
Techno's not really much for physical stuff, and is probably demi or gray sexual, and probably demi-romantic as well. It's not something he thinks about much. He loves his wife, and wishes she'd be a little less affectionate (especially in public,) but he doesn't mind much and likes keeping her happy.
His wife Rosalie is pansexual, and while she actually has thought about it she doesn't see it as important. She's pretty much been obsessed with Techno since they were hatchlings, and hasn't really bothered to think about other people much.
Myra is asexual, and dislikes most physical things. Her husband is perfectly happy letting her set the pace for things, and is usually happy as long as she's happy. She did decide to have children, and is very protective over 2/3 of them. (One of them was basically disowned.)
Flash is pansexual, and occasionally winds up acting flirty and gets yelled at by his girlfriend. He's actually very committed to her, he just slips sometimes and accidentally winds up flirting with some cute dragon.
Kazimir and Horizon are both bisexual and prefer girls. Prior to meeting Horizon, Kazimir was a disaster at dating. First he tried hitting on one of his female friends, but she had a thing for her penpal, then he hit on his friend Whisper, which freaked the poor straight guy out, then he hit on the clan medic, and she sprayed him in the face with antiseptic. He finally did get a girlfriend though!
Glitch and Grim are rather androgynous, but I doubt either of them have put much thought into their gender identities. Glitch refers to herself with feminine terms, and Grim uses masculine, but they've been known to respond to anything if it seems like it was directed at them.
Lumina is bisexual, and flirts with everything. Including familiars. She doesn't mean anything by it, it's just how she communicates. Everyone's pretty much used to it. When she's around someone she's interested in, she just stands there awkwardly saying nothing.
Thalia is probably bigendered and/or genderfluid, and is fine with any pronouns. He hasn't really put much thought into his gender identity, he just knows that he feels sorta like a girl, and sorta like a boy, and that sometimes the balance tips more in one direction. He gets really annoyed if people switch from feminine terms to masculine ones mid-sentence. He doesn't know why, he just does. Thalia is only romantically interested in females.
Marcus is a gay transboy. Since he presents as male, and most of the clan isn't very familiar with Mirrors, most of the clan is unaware that he is biologically female. Only a few that are slightly more familiar with the breed noticed, and they felt that it would be rude to mention. He's dating a cute little Tundra.
Diana is in the midst of a small identity crisis. She's considered herself a lesbian for her entire life, and has only ever been interested in female dragons. Until she met Arne, who in her defense she originally mistook for a girl. She has begrudgingly admitted to herself that she likes him, but has yet to figure out what this means for her. She's never been interested in a guy before, and Arne looks and acts extremely feminine, so mostly she's extremely confused. (And secretly hoping that Arne may turn out to be a transgirl.)
Those are the most notable of mine, and I'm sorry that this post turned huge... ^_^' most of them don't have proper lore written for them yet either...
