I'm still pre-transition (physically, at least.

) and wondering if, when, how, and how much. Internally I feel female and usually feel like I am masquerading as a male. Every day I wake up wanting to be fully female. But every once in a while I actually feel male for a few hours at a time.
I have a question for my post-transition sisters:
Did your sense of identity fluctuate before transition, and if so, did it also fluctuate after transition? Did it happen differently at different stages, such as before or after GRS?
