I've thought about this for a long time, as long as I've actually accepted that I was trans.
At first, I thought that I could only be either or: male or female. Because of this, I accepted the idea of having a male life and a female life, each independent of each other. It was rather difficult to have two separate lives that never overlapped, and it was taking a toll on me.
I then began to take a look at the importance of presenting as either in my life and tried to see if there was any sort of reason as to why I needed to continue presenting exclusively as either gender. The reasons were very fickle, so I started examining my personality and what separates me from other people of each gender.
I found out that, despite my family's best efforts, that I have blended the qualities of both men and women as I've grown up. I can be strong and assertive as a man, but I can also be emotional and understanding as a woman. I then went back to the drawing board and re-examined my rationale and what would be better for me, as presenting as one gender became increasingly trivial.
My sexuality was only mildly in question. I had experimented with people with the same birth gender as I and found my experiences with them to be dissatisfying. So in that sense, I am
straight. However, I can kiss someone of the same birth gender as I and disassociate the action from its implied meaning, which not a lot of people can do.
In the end, I realized that I am a unique individual who's able to embrace being both genders at the same time at any given time. I can't conform to a social standard because there is no social standard for androgynes, and who's to say that I have to anyway? My work accepts my new fashion, as they see it, and I can use either my male or female voice to present appropriately depending on social situations.
As far as my birth gender goes, well, that's a mystery
