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.
I dual booted my study pc. Well technically I did. I didn’t use windows for a few months without thinking about it and by then I was too afraid of windows corrupting my linux if I ever booted it. So I effectively just had a Linux machine with half half the disk space. Never had a problem with it though.
