My partner just came out to me as... Not cis... But he doesn't have the language at the moment to communicate exactly what his needs are.

We've been together for 5 years and I just came out as a lesbian. He has been unbelievably confused about why I would feel like being a lesbian excluded me from dating him. Something he said last night clicked for me. It is abundantly clear that he doesn't identify as a man. He too feels like a lesbian.

Are there any very very basic resources that could help us figure out what his needs are? I want to help him with the tools and language he needs to communicate how he feels and what he needs from this point forward. I don't yet know if he is a woman, or if he might be non-binary, he is so deep in cisheteronormativity he doesn't know himself. Everything from the basics of the identities out there to what HRT is for would be incredible.

There is so much bad information on the Internet and I really really don't want to get this wrong. He deserves to be able to authentically express himself and I don't want to accidentally influence him poorly.
