This is the second act in this wonderful play.

Once well together, and the organs perfectly settled and adapted to each other, the third act begins, namely, the motion of the organs—the sliding of the penis back and forth, partly in and out of the vagina, though this is not really the best way of describing just what should take place. What should actually be done is, that the two organs should engage in this motion, which is common to them both. They should mutually slip a few inches, back and forth, each party to the motion doing a fair half.

It is often supposed, by both an uninitiated husband and an "innocent" wife, that all the motion should originate with the husband—that he should slide his penis in and out of the vagina, while the woman should lie still and "let him do it all." This is, however, a great mistake, and one that has caused an endless amount of ill to untold numbers of husbands and wives. And for the following reasons:

In the position just described, if the wife has her arms around her lover's body and her heels in his knee-pockets, while he supports himself by his elbows and knees over and above her, resting none of his weight upon her, it is perfectly easy for her to lift her hips up and down, or sway them from side to side, or swing them in a circling "round-and-round" motion, as she may choose to do. She can thus originate her half of the in-and-out motion—a something she will delight to do, if given a fair chance. If, however, the man lies heavily upon her, holding her down with the weight of his body, the possibility of such action on her part is prevented, and this results disastrously to both parties. And so, in this part of the act, the husband should take the utmost care to give his wife the full and complete freedom to move her hips as she chooses, and as a successful climax demands that she should.

Now if the wife be left free to move, as just described, and the in-and-out motion proceeds as it should, what immediately follows will vary in a great degree. Thus, the time taken to reach the climax, or last act of the performance, may be a few seconds, or several minutes, may require a mere half dozen motions, or several hundred! All depends on the intensity of the passions of the husband and wife, especially the latter, and their skill in manipulating this part of the act.

The effect of this motion is to still further excite and still more distend all the organs involved. Normally, the motion grows faster and faster, the strokes becoming as long as the length of the organs will possibly permit without separating them. The flow of the lubricating fluids, from both organs, becomes more and more copious, till, all at once, the orgasm, or fourth stage, is reached!

It is difficult to describe what this orgasm is like. There is no bodily sensation that at all corresponds to it, unless it be a sneeze, and this is only like it in that it is spontaneous, and a sort of nervous spasm (a sneeze is sometimes spoken of as an orgasm). A sexual orgasm is a nervous spasm, or a series of pulsating nervous explosions which defy description. The action is entirely beyond the control of the will, when it finally arrives, and the sensation it produces is delectable beyond telling. It is the topmost pinnacle of all human experiences. For a husband and wife to reach this climax, at exactly the same instant, is a consummation that can never be excelled in human life. It is a goal worthy the endeavor of all husbands and wives, to attain to this supreme height of sexual possibilities.

On the part of the man, the orgasm throws the semen into, and all about the vaginal-uterine tract. The amount of semen thus discharged at a single climax is about a tablespoonful, enough to entirely flush and flood the area into which it is thrown. Its use and action there have already been described, and so need not be repeated here.

On the part of the woman, the orgasm causes no corresponding emission of fluid, of any sort, that is jetted forth as is the semen. Yet the spasmodic action of the sexual parts, so far as nervous explosions are concerned, is exactly like that of her partner. Palpitation follows palpitation, through all the sexual area; the mouth of the womb opens and closes convulsively, the vagina dilates and contracts again and again, and the vulva undergoes similar actions. The sensations are all of the most delectable nature, the whole of the woman's body being thrilled, over and over, again and again, with delights inexpressible. This, however, seems to be the entire mission of the orgasm in woman. It has nothing whatever to do with conception; though many people, especially young husbands who know just a little about the phenomenon, believe that it is an essential to pregnancy. But such is by no means the case. All that is needed to bring about conception in a woman is the presence of the ovum in the uterus, and its meeting semen there, and so becoming fertilized. So far as becoming pregnant is concerned, the woman need have no pleasure at all in the act of coitus. Indeed, women have been made pregnant by securing fresh semen from some man and injecting it into the vagina with an ordinary female syringe!

The false idea, which largely prevails, and which usually takes the form that there is no danger or possibility of conception unless the orgasm is simultaneous on the part of the man and woman, has caused many a woman to become pregnant when she thought such a result to be impossible, because she and her lover did not "spend" at the same instant. For the same reason, many a young husband has impregnated his wife when he least expected to do so, thinking that because he alone experienced the orgasm, that therefore conception was impossible.
