I really, really can't see the attraction of this. One of my most basic rules is that you dom men by stopping them coming and women by forcing them to. Any vanilla idiot can not bring a woman to orgasm.

OK, making a sub wait a few minutes (which may feel like years to her) and making her beg is good. But it's so much more fun to make her beg to not be made to come again when she's already on sexual overload.

Women in an unsatisfying marriage will tell you that they cope by locking their sexuality away and trying not to get turned on at all. Where is the fun in teaching a sub not to feel sexy?
