Do you have any ace characters?
I have one character who is actually asexual where he isn’t in any way, shape, or form attracted to other people: Kaalhist.
Then I have a few characters who aren’t asexual exactly but for one reason or another aren’t interested in that kind of stuff:
Boc’afa - Master Jedi, practices celibacy and is careful about his attachments. He did fool around a little as a Padawan but that was stopped quick and he doesn’t even bat an eye at anyone any more.
Zib’aezi’lux - Flower Chiss Biotech but also occasionally works on the field as a sniper. He considers his projects his life and most people, and casual intimate relations, a distraction. The only exception are the few friends he’s been willing to make. I don’t even know what his preferences might be other than “Chiss only”.
Si’inau - a Jedi by now, did somewhat pursue a romantic relationship during the war and was crushed when he died; he was a young soldier. She continues practising more proper Jedi things but does have a close relationship with her Jedi friend Katsenittsi.
Sujj - Yuned’rar’s childhood friend on Tatooine is much too busy cracking his head open in pod racer crashes. He gets a little jealous seeing others in relationships sometimes but he doesn’t seem to have any interest himself to try and do the same. If a pretty girl or guy comes by, he’d rather just kick their face into the ground and then have drinks after. Also, said girl or guy should be a sturdy species.
