For me it is more about being dominated or humiliated in private (overt) or public (subtle) ways.  It can be but doesn't have to be sexual.  Being placed in subservient, menial, degrading, etc. situations does not directly give me pleasure.  It is the fact that I am forced into these circumstances and must accept them and play them out that is the turn on for me.  I am very open minded with a few limits but not many.  Looking to explore these interests with sane, down-to-earth people.
