Sexual arousal arises from an appreciation of eroticism

Much of what is known about female orgasm comes from women’s experience of masturbation. I found Shere Hite’s conclusions useful because they accorded with my own experience.
Shere Hite compared female masturbation with vaginal intercourse to explain why the lack of genital simulation (of the clitoris) would be likely to make it difficult for women to reach orgasm with a partner.
It did not explain why I have never been able to orgasm from clitoral stimulation with a partner, for example, purely from manual stimulation of the clitoris or through oral sex. Of course, the other characteristic of masturbation that is missing during sex is fantasy. That is unless a woman finds a way to incorporate sexual fantasies into her sex life.
It was some time before I came across the fact indicated by surveys that many women do use fantasy to orgasm during sex with a partner. Frankly I was amazed because this was something I had never really considered. The context of sex with a partner was inappropriate for my use of fantasy, which required a highly focused state of mind.
“Many times sexual fantasies are used to induce or enhance sexual arousal, and while fantasies are often combined with masturbation to provide a source of turn-on when a partner is not available, fantasies are also extremely common during sexual activity with someone else. For instance, one study of 212 married women found that sex fantasies help many women achieve sexual arousal and/or orgasm during sexual intercourse.” (p416 Human Sexuality (fifth edition) 1995)
Women use sexual fantasies both alone and with a partner
The realisation that some women do use fantasy during sex (and I was able to confirm this with a few of the woman I spoke to) allowed me to see a parallel with my experience of orgasm from masturbation. I realised that although I used clitoral stimulation during masturbation it only worked when combined with the use of sexual fantasies.
Sheila Kitzinger made the point that sex, especially sexual arousal, is primarily in the brain. I then realised that most accounts of sex focus heavily on PHYSICAL stimulation techniques and that PSYCHOLOGICAL arousal tends to be simply assumed or overlooked. I concluded that this is probably because psychological sexual arousal for men is usually a given.
My suggestion is that just as men need EROTIC IMAGES and stimulation of the PENIS for orgasm, women need EROTIC STORIES and stimulation of the CLITORIS for orgasm. This is my explanation of how I have reached that conclusion and how it fits with men’s experiences of sexual arousal and orgasm.
It makes sense that women will need to use fantasy more than men to reach orgasm during sex. Women have much lower levels of testosterone, the hormone that boosts sex drive. Also the naked male body does not cause women to become aroused enough for orgasm (otherwise women would buy porn as men do).
There is no logical reason why sexual fantasies should not be a part of our sex life (whether or not admitted to a partner). This conclusion helps explain why foreplay techniques may not be as effective as we would hope because, just as during female masturbation, women’s sexual arousal relies on sexual fantasies.
