@lennby I think I originally asked for more info because some of the initial wording read to me like a "I must have some amount of boy to be non-binary" thing, a phase I went through myself for a while before accepting I'm basically a demigirl and my decision not to pursue HRT is effectively a compromise I'm choosing to accept.
I'm surrounded by transmascs in my social circle. I celebrate their transition as they celebrate mine, but I suspect we must mystify each other at some level.
