I learned something important after almost 3 years of living full-time, even at work, as female.
My personal experience is that for the first year, I was hell bent on learning how to be the ideal female; I do not regret this as it taught me so much. But, just like you, it felt as if something was missing. Though in my case, I was missing the point, so to speak.
It felt as if I was acting and in my head, if I want to be myself then I shouldn't have to "learn" how to be anything. All I needed to do was act naturally, but this time, without restraint or fear.
This is were I possibly make you and some other people angry. Transgender, asexual, bisexual, male, female, etc..., they are all trying to appeal to there selected term, whatever it may be, and it kinda upsets me because the whole point of these journeys is being yourself instead of appealing to a certain label.
So, My advice to you is; If you REALLY wanna know what you are, just act naturally without hesitation or regret. The best label in the world represents you 100% and it's your own name.
