I consider myself polyplatonic and polyalterous. I have squishes on multiple people. And I would like to be emotionally intimate, in a way that cannot be wholly described as platonic or romantic, with more than one of my squishes. I believe that I'm also heteroplatonic, since all my serious squishes so far have been women (I've had a passing squish on a non-binary person, and then a passing squish on a guy).
I think that platonic orientations are just as diverse as sexual, and romantic orientations, and that a lot of prefixes for sexual/romantic orientations can be applied to platonic orientations as well.
