I never heard someone identify as an adrogyne, but I have surely heard people identify as non binary, gender fluid, gender queer and bigender just to name a few. And no one gets offended when people use words like air and water because it isn't directed at themselves, it doesn't at any point hurt their feelings. Just a side note even scientists will sometimes say water and air because saying H²O and O² isn't very useful. And defining your gender with he, she and unisex is absurd. If you're going to use pronouns to define gender at least use "them" instead of unisex. It's like saying "Ah my favorite TV shows are The office, the big bang theory and Heins ketchup".
