Anemone is a lesbian. Growing up sheltered meant she didn't get the chance to play with that many dragonets her age, so crushes weren't a big thing for her. Whirlpool's advances scared her, to the point where couldn't imagine herself dating a guy. She's a little surprised when she gets feelings for Tamarin, but no way is she going to let them go.

Pike is straight, but he's absolutely the best ally. He used to have a crush on Anemone, but once he realises she's a lesbian he helps her out.

Peril is a literal flaming bisexual, but Scarlet's strict upbringing means she's never had a chance to act on any crushes. The idea of another dragon liking her back kind of startles her.

Tamarin is demisexual and panromantic; because she can't see other dragons, it takes her a while to become physically attracted to them. She assesses them based on things like the sound of their voice, the feeling of their scales and how frequently they touch her (creepy leaning in vs gentle guiding nudges).

Coconut is aro/ace - fruit and suntime are more than enough for him, thanks. Marsh is aromantic too, so they get on pretty well.

Bonus - Sunny and Fatespeaker set up an ally network to help LGBT dragonets feel more secure. They don't tolerate prejudice of any sort and try to help out as much as possible. Fatespeaker is all about pride and pasting flags left, right and center. Sunny counsels confused or hurt dragonets. Starflight is a walking dictionary for any term you need to know, and also teaches allies ways they can be supportive.
