I was a boy in most of my life. I was in hiding most of it but I conformed because I was afraid of getting my butt kicked by the neighborhood kids everyday. I got in fights, played basketball (even though I thoroughly sucked at it)... typical boy nonsense. I didn't like myself, but I felt it was something I had to do. I had a secret life that nobody knew about, where I'd get on chat rooms to meet guys that would treat me like a girl. My mom found out about it at kept me from it, so I kept quiet about my life from then on out.
Life thru my teenage years was a giant mistake. It was the biggest mistake of my life and if I could do 1 thing different in life it would be to just suck it up and tell my mom that I loved girls clothes, I loved barbies, I loved playing house etc when I was 6. I was a giant wuss about it.
But I'm okay with it all. It doesn't make me any less of a woman now. I'm happily living as a female, almost a carefree lifestyle too (as far as you can say carefree for someone who is trans). In fact the guys I live with say I'm a bit tomboyish, and they love me for it. My tomboyish sister in law calls me a girly girl barbie doll, and SHE loves me for it.
In short, I am me and I'm okay with it. My past doesn't make me any less of who I am as a girl today. I don't think it makes anybody less of who they are as they see themselves. I don't see any reason to try to feminize who I used to be to validate who I am today.
