Book recommendations?

Do you know of any books to offer my spouse to help me explain gender fluidity? Sometimes I make a comment about how I'm feeling or a thought process that resonates as gender fluid. And. I'll tell him all sorts of things about my thoughts. But. Admittedly. I'm in an early stage of accepting my identity and navigating what that means for me. It sometimes puts me in a state that is unable to be questioned. He is most oftentimes accepting and loving. Although. A couple times he says some really insensitive things and doesn't know why it is inappropriate. Or he will misunderstand my statement and question me in a confused way that isn't easy for me to navigate.

While we end these conversations with mutual respect. The pressure of having to explain myself is overwhelming and I'd love to offer him some literature on gender fluidity and potentially a book specifically about how to support gender fluid people in their life?

Any help is welcome. Thank you.
