OK, I'm not too sure what you mean but I'll try.
I was born with male external genitals but from a very early age I identified as female. Obviously I was too young to make any decisions or even comprehend what male and female was. But I carried out typical female play and child interactions of a female. This BTW is not unusual, all children have both male and female characteristics and their social environment will have a big influence on their play and social interaction.
When I was sent to school I was sent to an all boy school, I was horrified, as I had no relationship or association with my fellow students, I was a girl WTF was I doing here?
At puberty I was waiting for my periods to start and for my physical changes, they didn't occur. It was at that time that I realised something was wrong. I told my parents that something was wrong as I wasn't changing physically into a girl. They did not understand.
I lived my life as a woman in a male shell, I empathised with woman, I tended to have a female personality and outlook. I tended to respond to situations in a way females respond rather than males. I had no interest in male orientated goals.
I was lost.
I wore female clothing I acted in a feminine manner and all of this was a natural reaction for me, I did not feel odd in doing this. I felt very conflicted when trying to be a guy. I felt normal and non-confused when living as a female.
Men were sexually attracted to me and woman in general were not, I had no sexual desire for men, but I had an interest in them. I had little sexual desire for woman.
Finally I sort help and very quickly was recognised as a trans* woman. I felt massive relief very quickly and going on hormonal re-assignment was a blessing.
I immediately went FT even though I had great fears. I am now a woman in mental and hormonal sense and when the opportunity arises I will complete the cosmetic change with SRS.
I have been asked and I have thought about the question of what defines me as a woman rather than a man. I honestly have to say I have no idea. I have never been a man and I find the question extremely puzzling, I haven't changed, I am what I have always been, the outside shell has been changed and yes I needed some therapy to get over depression etc that were associated with living in a conflicted psyche but me, I, the id, the 'soul' is the same. I was born a woman and called a male name and raised as a male, rather unsuccessfully! I named myself Cindy at a toddler's age, the age we learn our names, I do not know where the name came from, but it was mine and I just knew who I was.
So to answer your question, I was born female in a male shell. Hence I identify as female. From accepting and being me and living as me and everything about me I do now have sexual interest, I'm attracted to guys, straight guys. Possibly I was asexual for so long because I couldn't relate to my preferred sexual partners and I now do. I'm a straight woman and a very happy one.
Please ask away if I have missed the point of your question.
Hugs
Cindy
