Even fights really do it for me, IF the 2 women are actually even in height, weight, age , and abilities and both women want to and know how to fight. just something about a long back and forth fight between 2 women where the outcome of the fight isn't clear till the very end, a test of stamina and who can take more punishment and still get up and fight back, keeps you on the edge of your seat. And I'm sure women feel the same way if it was there guy on the mats against an equal male opponent.
