I agree with cadence. I have been submissive all my life and have had submissive sexual fantasies as early as I can remember, ones that involve kidnapping, rape, being held against my will, being forced to surrender/submit, etc. Yet, I was not physically or sexually abused while growing up. I didn't suffer abuse until I was in my first marriage, which was vanilla. My ex was the one who subjected me to emotional, verbal and physical abuse. But none of that was a turn on for me and none of it made me more submissive.
I have never been one to analyze why I am the way that I am. I just accept my sexuality for what it is and enjoy it. I believe that sexual submissiveness is something you are born with. If something in my past made me this way I have not come across it. But I do know that it was not former abuse on anyone's part that made me a sexual submissive and masochist.
