I think there needs to be a distinction somewhere between some Dominatrices (who you seem to be referencing) and the majority I know. You seem to be thinking that a pro does it as if it were a chore (and in some cases it may be - I do know there are some 'pros' out there who are not really Dommes but only pretend to be them and think that all it takes is a way of dressing and I do not think these women would enjoy it all that much) whereas my experience has been that Pro Dommes are Lifestylers who just happen to have created a job for themselves where they get to be paid a lot of money to have fun doing what they love. You can generally tell these from the way they work and react to things - they generally follow SSC or RACK guidelines closely, they don't react well to being given a script preferring to plan thier own sessions (suggestions about what you like are different, thats not a script), they have their own subs who they play with when they are not working and so on.

Sort of wrenching this back onto topic somewhat... I think the Pro Domme thing as described above is in fact a perfect example of what Jennifer is talking about. When you go to a Pro you expect certain things and there is a difference between someone who is purely in it for the money and someone who enjoys what she does. One is merely topping while the other is Dominating.
