It really is interesting. bryan'sgrrl and I were looking at bdsm porn over at this morning, when we realized that I'm more interested in pictures of girls faces- when they look a little nervous(because that face or a whimper isthe hottest thing to me). she likes to see that strong Dom arm or face.
and Oz, I think you are right about the "topping from the Bottom thing. if I had a sub who thought they could control the scene we were in, I would love it- it's a chance to disabuse them of the idea they had that power. communication needs or desires is fine. but if I'm in charge, I'm in charge.
