I would have thought any escorts that do weights are doing it for toning purposes rather than to develop muscles like a butch lady type!
Seek and you shall find!
Women won't build muscles to the size of men from bodybuilding naturally. They're going have to take testosterone among other things to really become butch to be honest.
I have a serious fantasy about girls who work out seriously, particularly those who squat regularly. Makes me weak at the knees.
