This leads a woman to be focussed on her relationship with a man, to be turned on when she feels safe, protected and provided for, and not turned on when she doesn't. From whatever perspective we come from, it is clearly more important for most women to have more time to feel safe, protected, loved, cared for, and special, in order for them to reach orgasm. Foreplay for many women starts a day or two before the sex act, with the man showing them special attention and love, which begins to put them in the mood for love. Men usually do not need such a long time to get ready. Women do have higher rates of anorgasmia then men but this estimate of the prevalence for men is probably too low.
Nobody actually knows why men have a lower rate but there are at least two types of theories.
Thus men who could not orgasm did not reproduce and this over millions of years resulted in lower rates of anorgasmia for men. These types of theories are not mutually exclusive. My guess is that anorgasmia relates to a lack of efficacy and control in one's life. Orgasm requires becoming vulnerable and open. Most experts agree, too, that female sexual response is more complex overall than male sexual response, and this may, in part, account for the vast difference in the percentages.
