After reading this thread, my opinion is that virtually all of the criteria for being one or the other besides the physical may suggest that I am actually a male which I am quite sure is not the case.
I think many of the things we use to determine gender are base on how we are raised and the local culture and it is impossible to say 'oh you do XYZ you are a woman (or man)'. It is how you feel, what you feel not how you act, how you respond or speak.
The few transgender people I have spoken to in person have explained a feeling their entire life of being trapped in the wrong body, never feeling quite right in their own skin until they realized why and began the process to change. not one of them said 'well I am caring, I am emotional when intimate, so I must transition'
