I've always had submissive desires (I won't say tendencies - because I'm very dominant in most every area of my life).
I can remember being in kindergarten and enjoying playing the "locked up princess" who was stuck in a cage. I would just sit there in that wooden "cage-like" piece of play equipment begging for the boys to "let me out".
Another one was running from the boys and letting them tackle me and struggling to get away. That was always fun, getting captured and whatnot.
Even in my teens, I enjoyed make-out sessions that were rougher - more cat and mouse, hold me down, etc. I *liked* aggressive boys.
Later on - I liked older, more aggressive men.
It wasn't until my early 20's that I discovered the term "BDSM" and that there were other people out there who enjoyed REAL activities that made sense and that these fantasies weren't just made up in my head.
It was like a light switch being turned on inside my head.
I haven't turned back since.
