Thanks for this post!
I would strongly recommend Stone Butch Blues by Leslie Feinberg. It's a work of fiction with autobiographical elements, that follows the life of a stone butch lesbian in the late 20th Century. I will warn that it may be triggering to some people due to the various forms of violence and bigotry in it.
Also, I would recommend dabbling in non-fiction and queer theory. Audre Lorde is one of my favourite writers, and her essays like "The Master's Tools Will Never Dismantle the Master's House" demand the consideration of subjugated voices, like those of Black women and lesbians, in feminist discourse.
