It is not female sexuality that has a problem (‘dysfunction’) but society that has a problem in its definition of sex and the subordinate role that definition gives women. (Shere Hite)
Thanks for commenting! Actually it is her mind reacting to emotional stimuli. A woman offers sex in exchange for a loving relationship primarily. A few women offer sex for money, ego or vanity - to be popular with men. Usually heterosexual men have to pay directly or indirectly for sex.
Thanks Monica so much for commenting. So much silence on this topic from women. Both Kinsey & Hite concluded decades ago that women have sex to create or maintain an emotional bond rather than for erotic reasons (as men do). People forget that sex is primarily about reproduction. Sexual pleasure is merely a by-product - for men. A women needs to find a man who is devoted to her and willing to support a family for many years. She uses sex as the means of keeping him committed to the relationship. No man will stay with a woman for long who does not provide regular intercourse.
Marital intercourse is an artificial construct that has evolved to make it more acceptable to women. The missionary position involves a man being proactive while a woman needs to make little effort. This explains the huge difference between male fantasies and marital sex. Men hope for erotic turn-ons that involve a woman making special effort. Most women don't even realise that they could consider making conscious effort to make sex more exciting for a man. Usually women have to be paid and instructed to do this. I have been a proactive lover because I know that my partner enjoys any sign of presumed female arousal and because I love him. But it is a conscious decision because there is no arousal for a woman with a lover.
