I figured I'd just respond here :3
I know what you mean, I was never really competitive either. I used to be terrified to lift heavy things out of fear that I would develop big muscles, as opposed to most guys who wanted to show that their's were the biggest >_>
My earliest memory was of my fascination with ballet... I just remember it being a 'girly' thing, and thinking that I wasn't allowed to take it, even though I really wanted to... Then wanting to dress as a cheerleader for Halloween one almost every year, but not saying anything >_<
