Ahhhh, but the reason why we might want that has everything to do with the answer! And so very few people have even the faintest idea of why they feel the way they do. Which is understandable; it took decades for me to figure myself out.
So, for me: "Do you want to become a woman/transation?"
I have the desire to become a woman. I have no desire to transition. The desire to become a woman is a result of being brought up believing that I was supposed to be female, so, stuck in my mind, is the idea that my body should be & present as female, which results in the incongruity of wearing men's clothes. Unfortunately, just feeling like I'm supposed to be female doesn't 'fit' with everything else. Nothing else about me is female. I don't think like a woman, I don't communicate like a woman, I don't experience the world like a woman, I don't see relationships like a woman, I'm sexually turned off by men, I'm sexually turned on by women, I don't 'nest', there's more but I think you can get the point. The only female thing about me is, I feel like I'm supposed to be one, all because of what was continually reinforced through my childhood and adolescence. I believe that something about our sexual self identification becomes permanent at some point during our development, in a similar way that our linguistic accent becomes permanent after puberty. I cannot tell you exactly when it 'finalized' in me. But even though I now know that I am not female, the feeling that I'm supposed to be, never goes away. You can read more about it in my bio, link is in my sig. It's about a ten minute read.
