While I'm comfortable with playing characters who aren't aspec, my two bards are both aro specifically for the fun of messing with the trope.
One of them is very extroverted, confident, and friendly, and in doing my darndest to portray that when I am not so much those things, it apparently it comes off as accidental flirting sometimes. It's nicely in character, really, as they're totally romance oblivious unless it's spelled out for them.
Fortunately my ttrpg friends are all queer, some of them also aspec, so there aren't any issues over my or others' aspec characters.
