One problem with any of these labels is that defining oneself as such has a tendency to limit oneself.
If you step back for a moment, and think about what cis-gender women and men are, there's quite a variety. While I do use genderfluid as my label, within this community, and elsewhere if I'm really cornered, though I am just me. Most often, I just am who I am, and the way most see me is as a guy who wears long hair, earrings, makeup, and feminine clothes.
I've always been more like a girl than a guy, but not completely a girl. I'm in my early forties, and for most of my life, I'd never even heard of these labels. I still was the same person back then though, I can't even fake being a guy all that well.
