3, 4, 12, 13, 19 for Caelus for the meme
3. what are some features of others that attract them from the outset?
Definitely eyes to begin with. Though vibe/personality counts as much. For example, someone like March or Qingque is too loud or too hyper at times. He leans more towards the type like Dan Heng, or Aventurine, or even almost Blade. Not that energy bothers him, but he gets overwhelmed if it's nonstop.
4. what are some features of others that arouse them, or they find arousing in a sexual situation?
Ass. Though honestly, simple things like if there's sexual tension and they're simply making out, he's focusing on the look in their eyes or body language even. Especially if they bite their lop or his lip in the process.
12. how do they feel about one-night stands?
He isn't opposed, necessarily, but 9/10 unless he's just absolutely desperate, he'll avoid the option or situation. He'd rather have a connection than just a fling.
13. are they openly flirtatious/sexual, or are they quite private?
Private to begin with, but he gauges off his partner. If they prefer private, he'll do his best to follow that. But if they flirt or imply things in public? Oh he's returning it.
19. are they dominant, submissive, switch, partner/context-dependent, or unsure?
It's partner-dependent, but he'll stay to either a switch or submissive.
