I'd agree with the general idea that just because a woman is the Top is no reason for her not to get to have sex any way she wants. For some reason people have trouble seperating the idea of being the Top from always being the one on top in bed, so to speak.

After all, if a dominant female wants to order me as her sub to "get a bit rough with her" while we have sex, well that would be her call to make. :-) Or any other kind of sex she desired.

I've personally never been able to wrap my head around Dominant females that openly claim that they don't have sex with their subs, or what the exact appeal of a long term relationship with one is. It seems like an awful lot to give up for the sake of a bit of D/s. But that's just me.
