@tfproxy the way I've seen it explained is that desire for romantic relationships is a spectrum (from aromantic to demiromantic to yes please romance) apart from desire for sexual stuff (from asexual to demisexual to sexual) and desire for sexual stuff can divide further into desire for sexual stuff w/ others or a preference for solo only. I think people often use 'asexual' to cover that whole umbrella but it's actually really nuanced!
