I have never thought Rihanna was all that but lots of people do, including many on this board. I think it just shows how even a fairly small fetish like ours can have so many variations.
Give me a story with Kaley Cuoco or Katy Perry being roughed up and dominated by someone like Beyonce or Lindsey Lohan and I am a happy man. All in the eye of the beholder, I suppose.
