only 2 sex fights styles if you will are competitive or competitive fun, as for reach not sure it has a lot to do with it since most times the 2 women involved have thighs scissored and are on their butts sitting up as close as they can get to keep the contact and motion going , or on top of the other or rolling as one , reach might help in the pre start but if the 2 doing the fight are doing it right they usually are tasting the others breath on their faces, in my opinion the best method or advantage or way is to snake as much of your extremities around your opponent as you can to both keep her close and to use your power and lust to dominate her own, other than that use every arousal point on the body and once you have a steady rhythm she feels don't stop press your advantage till she can not go on.
