It's already been stated. Women having any type of sexual drive, let alone one that rivals a man because she feels the need to masturbate, is seen as 'abnormal'. Likewise, a man who DOESN'T masturbate is seen as weird or non-existent. Because of this stupid notion that men have much higher sex drives and women have virtually no sex drive, people use this reasoning to make the assumption that women don't masturbate as often. How could they? Their sex drive isn't that high. Women don't really desire sex, they use it as 'leverage' right? Of course, that's all B.S, and it's based on B.S. reasoning.
