This sounds a lot like my reaction to questions in the test i got for autism (except it was writtwn so i just scribbled these thoughts out).
I don’t know if you are on the spectrum, but it sounds like the test giver would have been horrible at administering it to children on the spectrum either way.
I mean being romantic or sexual carries some other connotations and meanings making them ambiguous in many situations if used as the antonym to the asexual and aromantic label.
I don’t really care what words are used for it but I find the allo ones useful as they are the most commonly understood ones and are unambiguous.
