The research findings have been ignored. So we have no scientific (consistent and unbiased) account of human sexuality. Sex therapists focus on the emotional rewards in the wider relationship that may cause a woman to offer regular sex. They do not talk of sexual techniques: the anatomy involved in orgasm or the mental turn-ons that cause arousal. The sex industry makes money out of our sexual ignorance. But none of it works because if there was a solution to women's lack of sexual interest, it would spread like wildfire and no one would have to pay.
