Sex drive is nothing but 'spontaneous desire'

Emily Nagoski also found that while 70 percent of men typically experience "spontaneous desire", just 10 to 20 percent of women have "spontaneous desire" as their primary desire style.

"I think the reason we expect everyone to have 'spontaneous desire' is because that is how most men experience it," Nagoski, director of Wellness Education at Smith College in Northampton, Massachusetts, was quoted as saying in a Daily Mail report.

Men are the reason most women believe they should have a "sex drive".

"Every woman has her own unique sexuality, like a fingerprint, and that women vary more than men in our anatomy, our sexual response mechanisms, and the way our bodies respond to the sexual world," she said in her new book titled "Come As You Are".

Women should not judge themselves against others sexually at all.

"We never need to judge ourselves based on other's experiences. 'Spontaneous desire' is not necessary for sexual pleasure," she said.

According to her, women often experience desire as responsive, emerging in response to, rather than in anticipation of, erotic stimulation.

"Arousal first, then desire," she said.
