I really can identify with a lot of experiences you all have mentioned, but not all of them.
One of my earliest memories is praying to wake up as a girl, and wearing a t-shirt around my waist as a skirt at the age of 4. And the bump in the front didn't make sense, so I used a rubber band to tuck it in.

The cross dressing really kicked in when I was around 10 or so. Whenever my mom would leave me at home alone, I was in her closet as soon as I knew her car had pulled off the street. And the desire to "get my vagina installed" started around high school, and that never went away.
I never had the extreme body dysphoria or the depression that others have experienced. And I've settled into the guy role fairly well. So because of those two things, I never really thought I was trans. And it wasn't until just a few months ago that I put everything together and finally realized that I definitely am. Most people didn't cross-dress as kids and then spend their whole life wishing they had different genitalia. So even without the suicidal thoughts and crippling depression, I am trans.
