Oh never went through that stage strangely. 
Were you checking out DILFS?
Not at 13.
I didn't really become sexual until I was 15. (as in have sexual thoughts and develop fetishes etc.) 
I was 12 when I first started having sexual thought, but I can remember waaaayyyyyy before that is when my fetishes developed. IT wasnt sexual yet, but I liked to wet myself and play games like that with other children for as long as I can remember.
and I remember playing bossy games, and had my boy friend stay sealed up in a box. He liked it. I'm sure he grew up to be a sub.
