There are some men and women so constituted, nervously, or by temperament, that they are _obliged_ to rigorously _limit_ their acts of coition. Some men cannot engage in the act more than once or twice a month and maintain their health. For them, the act draws on their vitality so severely that it quite upsets them, in almost every case. During the act, they are subjected to nervous shocks, they "see stars," and undergo rigors and nervous sweats which are severely debilitating. Often, too, they will lie awake all night after engaging in the act, and be more or less of a wreck for a day or two afterwards. Some women, too, are of a similar nature of organization, and undergo similar experiences. Of course, in all such cases, unusual care should be taken never to reach the point of excess. It is unfortunate if people are married who are ill-matched in this regard, especially so if the difference between the two is of a pronounced nature, as when the husband or the wife is very amorous and virile, while his or her mate is unable to engage in the act, to any considerable extent, without suffering therefrom. If such case arises, the best should be made of the situation, the more robust party accommodating himself or herself to the incompetency or inability of the other, and the weaker one doing all that can rightly be done to strengthen and develop his or her infirmity. If this is done, _the chances are many to one that, as times goes on, the parties will grow more and more alike--the strong becoming more docile and the weaker one more robust. Take time, love each other, court and be courted, and only the best results trill come of it all_. Now there are some women who are called "anesthetic," that is, they have no sex-passion, though the sex parts may be normal. Many physicians declare that as high as forty per cent of the women _who are reared in modern social life_ are thus lacking. These women engage in coitus, though they get no pleasure from the act. They never reach the orgasm, and have no sensation of delight from the act; they seldom secrete the pre-coital fluid, and hence the union of the organs, or their motion, are never easy or pleasurable. They can become mothers, and often such bear many children. Such condition is greatly to be regretted, and many women suffer greatly from this cause.
