I remember being confused about sexuality: I couldn't be gay because I also liked women, so I must be straight. Then I realized there was a word to describe attraction that's indifferent to gender. Also turns out I'm nonbinary, which handily resolved similar confusion over gendered expectations.

Anyway, you might be an ambivert. Society tries to shove us into neat, easy to reason about binaries, but humans just aren't binary. We exist largely on bimodal distributions and most people aren't all one or another of any particular thing.

Right—I perhaps should have been clearer about this in my own post. It's definitely a spectrum, not a binary, though I'm not at all sure the distribution is normal (ie, a bell curve). I don't have any actual sources on that, though, and I'd be very intrigued to see a scientific study giving a population-level distribution of those traits in particular.
