This is yet another big hoax! The difference in desire between men and women does not involve the amount of desire, but the quality of it. For example, a woman’s arousal is distributed throughout her entire body, not just her genitals. Even erotic fantasies are different between men and women.
Women’s fantasies are generally more emotional, sentimental, tender and affectionate, with a tad of exhibitionism and narcissism thrown in. The images are more abstract and imaginative. Women imagine real, personal stories.
Male fantasies are usually more explicit than female ones. They are more visual, with genital images, and detached from any emotional context. The classic male fantasy of sex is desire in its purest form – a purely physical gratification.
