I've created the Aro community on blahaj, but I've found there's just not much to talk about.
How do you talk about something you don't feel or do?
One thing I'd be interested in is research into the causes of aromanticism, but last I checked there's literally zero academic research that treats it as distinct from asexuality.
I expect a strong link with autism due to the involvement of oxytocin.
Maybe I should run a poll in aro communities to check my theory, but I'm afraid that sample size and bias would make the results meaningless.
