I'm not trying to argue with you (really, I'm NOT!) - but what you wrote above has me scratching my head.
I'm born male. I present to the outside world as male. I've had a lifetime of acting/thinking like a male.
But I've always felt in my "heart of hearts" that I'm not (or should not be).
My soul cries out "but I'm a girl!", so I guess at that at least some level I identify as female.
So when do I say I'm crossdressing - when I'm in jeans and a t-shirt, or in a blouse and skirt?
I always thought that cross-dressing was wearing clothes associated with the the gender opposite that of one's (current?) body.
Dang - this definition stuff gets so-o-o-o messy.
