My kink is to play the role of submissive slave to dominant personalities.  Several of these roles in the past have evolved into sexual submission to strong black men - mostly due to the whim of the controlling party - although I will respect the authority of both men and women of any ethnicity when I am playing my role.  In public  I'm a fairly strong-willed personality who is control of most situations, so I find it a huge release to be on the submissive end when I play.
