What are some gender identities similar to nonbinary/agender?

I’ve called myself agender for a while now, but it’s never felt just right. I feel a connection to a lack of gender, and that there’s nothing there, but I feel like at its core, my gender is still slightly feminine. I’m not demigirl, and I don’t think I’m librafem, it feels beyond those. I’m so confused.

Any ideas?
