Many modern women who claim their dignity as human beings still grasp their sexual lives by referring back to a tradition of slavery: so it seems humiliating to them to lie under the man and be penetrated by him, and they tense up into frigidity; but if reality were different, the meaning sexual gestures and postures symbolically express would be different as well: a woman who pays, whodominates her lover, can, for example, feel proud of her superb inertia and think that she is enslaving the male who is actively exerting himself; and today there are already many sexually balanced couples for whom notions of victory and defeat yield to an idea of exchange.
