I have to laugh sometimes when people say they remember something that happened to them when they were 3 or 4 years old. I'm certain I did some really girlie things that age, but I cannot tell you that I remember.
Maybe if I had gone to kindergarten I would be remembering things that happened when I was 5. But I did not. Kindergarten was not attended by all kids back in the 60s. Sso the earliest I can think back to is probably age 6 when I was in first grade.
I had two older sisters and of course my mom at home. I do remember seeing them -- my sisters quite by accident -- in various states of undress. I'd go by their open bedroom door sometimes when they were changing and accidentally see that my older sister had little breasts and both were quite different from me down below.
Now my mom was different story altogether. She might be getting dressed after bath and the phone would ring and she would think nothing of going to answer it wearing just panties. Then, not thinking, she would go about doing some other things in the upstairs rooms still wearing just her panties. And I remember what big glorious breasts she had -- with big nipples -- and how I was awestruck when looking at them.
I will not tell you that at age 6 I knew I was transgendered because I did not know what was going on. I do know for sure that I wanted to be like my mom in all ways -- including her body. And like my sisters. And not like my dad.
