Dominant yes. I should know... every serious relationship I've been in has been with females who where into BDSM and dominant, or switch with a propensity towards to dominant. However kinky and dominant they may have been, it has never been raunchy in the same way that gay bath-houses or CL ads are. I don't even know how to explain...but like, they've always been oh so adorably cute and very loving and affectionate and never degrading or "dirty" in the more literal sense of that word...like no "uuunh yeah! lick my unwashed, unshaved cunt with blood clotted in the bush" type of deal. I've been to swingers clubs many times, and yes, I've seen some truly depraved hetero sex going on, although lots of it was pretty cute too, and I've only on a few occasions ever seen girl on girl that was raunchy.
It's not that I am arguing raunchy hetero or girl/girl does not exist, or that all gay people are raunchy, but that as a probability distribution over a space, one has a far higher chance of observing "gay" in the neighbourhood of "raunchy" than one does of observing MoF or FoF. One has very low chance of observing FoF in the neighbourhood of raunchy.
Alternatively put... In the same way that it's not always the case that a person with Kaposki's Scarcoma has A.I.D.S, it is quite unusual to find a case in someone who does not, and it's usually limited to a few other defined, small subsets of the population.
