The androgyne symbol and epicene symbol are not mine, someone else came up with them. I modified the genderqueer symbol a little.
Now I identify as a mirl under the genderqueer umbrella, but the genderqueer umbrella is, to my understanding, huge, encompassing all sorts of people who identify themselves differently.
The one I've been avoiding analysis of is androgyne. Physically it's a fitting descriptor for me, mentally it's not, as I'm not in harmony with myself as a woman at all. I also don't feel like it's right to describe me as I'm androgynous by chance, rather than it being an identity I embrace and express.
Epicene gives the sense of being more indeterminate. I find that sometimes I feel myself to truly be a girl, and see things as a girl, other times I feel as I'm simply and only an effeminate male, but mostly I'm in harmony with both simultaneously without conflict or exclusion. Because I don't feel as polarized between the two, and there's little to no involuntary switching between poles, I don't consider myself bigender--and it seems a lot of bigender people fluctuate between boy and girl or woman and man, or a binary gender and non-binary gender, or two non-binary genders, but, ones that are typical for their age. Nor do I consider myself genderfluid, since my feeling of gender identity and my gender presentation has been fairly static so far.
I guess also, even when I identified as a woman, my gender presentation was towards the epicene rather than androgynous---performing womanhood rather than being at true peace with at least part of it.
This is just my own understanding of epicene and isn't intended to conflict with any other definitions of epicene.
I know it's been a whirlwind as to the myriad labels I've taken up over the past few months, but I guess it really takes time to figure out who you are.
Given this information, I currently identify as an epicene mirl under the genderqueer umbrella under the trans* umbrella. : )
