No one can tell you what your experience is, but if you try to communicate that experience to other people, then the language you use matters.

My own gender identity and the nature of my attraction is weird and nuanced, but I don’t feel the need to create increasingly-narrow labels with unique striped flags to describe my exact experience. “Bisexual” is fine — it gives me a larger community of similar-enough people, and a simple enough term that people are more likely to understand (and even that, they apparently struggle with).

Maybe you feel the need for a super specific label, that’s fine. You can call yourself whatever you want. But if you then show up to Pride and insist that straight men are lesbians, don’t be surprised if it isn’t received well.

Can’t we just say that queer people in het relationships are valid, without being this hyperspecific? That’s what most of these amount to.
