I prefer some resistance in fantasy wrestling, I like the challenge. Obviously size/strength disparities may call for the sub to give less than their all in terms of fighting back. I hate to wrestle a limp noodle though hahaha. I usually find myself taunting during wrestling ("surely you can put up more of a fight than that"). Just check in with your Mistress (in this case I am referring to myself only, the other Mistresses may have other limits) now and then. I am not a trained MMA fighter, wrestler, etc and I certainly am not afraid to tell a sub to back down if their resistance becomes too overbearing.
