Again, if the wife is slow, and the man is quick, in this play for "getting together," it will enable the man to greatly extend and protract what might be called the time of his possible _retention_, if he can keep the foreskin over the glans penis. Some men cannot do this. If they have been circumcised, of course they cannot! But if the glans penis can be covered with the foreskin during all this playing together, it will enable the husband to prolong his "retentional time" far beyond what he otherwise could. Some men have the power of "retaining" to almost any length of time by the exercise of their will power, and so they can _wait_ for their wives. If the wife is slower timed than the husband, he should _carefully cultivate the "art of retaining"_ and so wait for her. _To do this successfully will greatly increase married happiness_. This same remark (keeping the gland covered) applies with equal force to the possibilities of the man's retention after the organs are united, and all through the third part of the act. If the penis can enter the vagina with its "natural cap on," the husband can give his wife the pleasure of many times the amount of in-and-out motion than he could otherwise bestow upon her. And if the wife is the slower of the two (as is generally the case) she will greatly appreciate such a favor, and will repay it a THOUSAND FOLD by the responsive, reciprocal motions which she will LAVISH upon her _considerate_ lover. This is an item of almost supreme importance--this "keeping the cap on" the penis, during the act, _if the wife is slower than the husband_--if they need to have a care, to insure their "getting off together." And here is a curious fact, which would seem to show that Mother Nature has especially provided a blissful reward for both the husband and wife who will be careful on this point. Thus, if the husband will be careful to have the glans penis covered with the foreskin (and, of course, this can _never_ be, if the organs are united when the vulva and vagina are dry) when it enters the vagina, and will so engage in the in-and-out motion that it will _stay covered_ as the _third_ act progresses--if this is done, when the climax comes, if the two "spend together," the womb will open its mouth as it were, clasp the foreskin, slip it back over the gland so that, when the supreme instant comes, the naked gland will be in the most direct and blissful contact with the most sensitive part of the uterus! This is a most wonderful provision of nature, and to utilize it, and enjoy it to its utmost, is the maximum of human delight!
