When the two have met and united, the usual result is that, after a longer or shorter interval, the man's mental and physical stimulation reaches a climax in sensory intoxication and in the ejaculation of semen. Where the two are perfectly adjusted, the woman simultaneously reaches the crisis of nervous and muscular reactions very similar to his. This mutual orgasm is extremely important (see also p. 58), but in many cases the man's climax comes so swiftly that the woman's reactions are not nearly ready, and she is left without it. Though in some instances the woman may have one or more crises before the man achieves his, it is, perhaps, hardly an exaggeration to say that 70 or 80 per cent. of our married women (in the middle classes) are deprived of the full orgasm through the excessive speed of the husband's reactions, or through some mal-adjustment of the relative shapes and positions of the organs. So deep-seated, so profound, are woman's complex sex-instincts as well as her organs, that in rousing them the man is rousing her whole body and soul. And this takes time. More time, indeed, than the average, uninstructed husband gives to it. Yet woman has at the surface a small vestigial organ called the clitoris, which corresponds morphologically to the man's penis, and which, like it, is extremely sensitive to touch-sensations. This little crest, which lies anteriorly between the inner lips round the vagina, enlarges when the woman is really tumescent, and by the stimulation of movement it is intensely roused and transmits this stimulus to every nerve in her body. But even after a woman's dormant sex-feeling is aroused and all the complex reactions of her being have been set in motion, it may even take as much as from ten to twenty minutes of actual physical union to consummate her feeling, while two or three minutes often completes the union for a man who is ignorant of the need to control his reactions so that both may experience the added benefit of a mutual crisis to love. A number of well-meaning people demand from men absolute "continence" save for procreation only. They overlook the innumerable physiological reactions concerned in the act, as well as the subtle spiritual alchemy of it, and propound the view that "the opposition to continence, save for procreation only, has but one argument to put forward, and that is appetite, selfishness."
