Do women really have an orgasm as a climax and a sensation of a very brief duration, as opposed to a feeling of satisfaction or arousal out of sexual acts they enjoy?

There is no need of such a “reward” to the female members of all species of mammals, as their body has no function of ejaculation or sudden push to make anything happen during the reproductive act. Hence evolution will not bring this particular sudden elation or climax to any mammals. This seems to be true regarding other mammals.

Have human beings evolved more and do our females also experience this?
We are not discussing whether women SHOULD enjoy or not.

I need to get the actual percentage of women who had experienced orgasm as described to get an indication to the answer I seek
