If you are a male-to-female transsexual, then you are female. If you are a female-to-male transsexual, then you are male. Or you may identify as both or neither.
But to add just a bit. It's who you feel you are. Take me for instance. I was born with female as my biological sex but I feel like I am a man. Yes, I look like a female but in my mind, I am male and always will be.
It's that "Don't judge a book by its cover" thing. I feel that represents Transsexuals the best because we may look like one thing on the outside, but on the inside, we are something different.
This is all coming from my standpoint as being a FTM, so if you don't agree, that's fine. Just remember its from MY standpoint.
