I have a few recollections that I was a submissive:
1 when I used to watch cartoons and someone gets captured I would roll myself in a blanket to pretend I was tied up. That would explain my mummification kink

2 my cousin and I would always play cops and robbers. Always wanted to be the one arrested.

3. Seeing videos of strap on sex really made me want to try pegging. My first try was such a disaster that it made me question my entire self. After over a year I sessioned with a more experienced dom who explained to me many things.
