Gender vocabulary, much like the vocabulary of many things that people tend to consider an essential an unchangeable part of themselves, is just a set of ideas, terms, and tools that can be used to describe oneself. It isn't a matter of categories. Even adding categories like agender, gender-fluid, gender-queer, etc. leaves you dealing with walls and limits that humans don't actually generally work with. Take what concepts and vocabulary you need from either or any gender category and use them as tools to find yourself.
For example, I find a gender dichotomy in myself based on the gravitas or importance of what I am doing. When being serious, working, being selfless ("You don't need a reason to help people" mode) being impressive, being dangerous (physically or intellectually) I use very traditionally masculine tools and traits. I express those parts of myself in an edgy and masculine manner. On the other hand, when I'm letting loose, having unimportant fun, being sexual, getting intoxicated, I express myself in very feminine ways. This is why I play MMOs as a gurl. I personify these modes very literally. I keep myself physically capable of presenting as either gender effectively. My female wardrobe is more and more competitive in size with my male.
However, like many people on the spectrum, I identify as more middle gender than either end. I just find fun activities and useful tools at both ends of the tunnel. I love playing with extremes, even when they don't necessarily reflect the whole me.
