You are always going to have someone not wanting to roll with someone...whether it's girl vs girl (not girl on girl!!), boy vs boy, girl vs boy). I don't think I understand the "disrespectful" part of it though - That seems a little odd. Usually guys don't roll with girls because they are either afraid to get beat by a girl or they feel they are getting screw out of having a "good" round (girls are too easy). If I guy ever says he doesn't want to roll with a girl because he "doesn't want to hurt her", that's BS. That is easily controlled.
