I’m Panromantic, Asexual, and Poly…is there a more proper way to say that?

Not really, as far as I know, because those words all refer to different aspects of yourself. You could think of them as your romantic orientation, your sexual orientation, and your relationship orientation. If I’m a sister, a writer, and a person who hates tomatoes, there isn’t one word that encapsulates those three traits because they’re all different aspects of myself.

But all words and all concepts were, at some point, invented by someone to reflect something they thought needed a word! So if you want a term that covers multiple aspects of identity, feel free to develop one!
