Just a thought Metal Angel,
Is it easier for a MtF to think it (wrong phrase but bear with me) easier or more correct or more natural then an FtM because that is your experience? It may be similar to how all "straight" people think. Why would anyone wish to be: long list. Do genetic guys think; I'm happy swinging dick why isn't anyone else (Paraphrase from "No Country for Old Men" great movie and loved the line: If the're coming for me, they'll be swinging dick).
Sorry, I'm rambling, writing and answering the phone at the same time.
Please no one take offense. I still believe the perception of our selves is individually unique. From anorexia, to body buliding to extreme plastic surgery, why do people do it? I've seen photos of people who know have feline features, someone with horns and a split tongue. Women with breasts bigger than their body.
This is not meant to get off the topic, but people see themselves uniquely. Physically, sexually, mentally, and any other -ally you want to tag.
So why do we identify ourselves as male or female?
The answer? No f***g idea, but we do.
Sorry if this got into a rant it wasn't meant too, I was having fun with a fun topic.
Luv
Cindy
