Every young married woman ought to know that the male system is exhausted in a far greater degree than the female by gratification. It seems, indeed, to have but little effect, comparatively, upon some females. But with respect to the male, it has been estimated by Tissot that the loss of one ounce of semen is equal in its effects upon the system of forty ounces of blood. As it respects the immediate effects, this estimation, generally speaking, may not be too great. But a man living on a full meat diet might, doubtless, part with fifty ounces of semen in the course of a year, with far less detriment to the system than with 2,000 ounces of blood. It is a fact, that mode of living, independent of occupation, makes a great difference with respect to what the system will bear. A full meat diet, turtles, oysters, eggs, spirits, wine, etc., certainly promote the secretion of semen, and enable the system to bear its emission. But a cool vegetable and milk diet calms all the passions, the venereal especially. Most men adopting such a diet as this will suffer no inconvenience in extending the intervals of their gratification to three or four weeks; on the contrary, they will enjoy clear intellect, and a fine flow of spirits. This is the diet for men of literary pursuits, especially the unmarried. As to the mischievous manner, it consists in the unnatural habit of onanism, or solitary gratification; it is an antisocial and demoralizing habit, which, while it proves no quietus to the mind, impairs the bodily powers as well as mental, and not infrequently leads to insanity. While the gratification of the reproductive instinct in such manner as mentioned leads to bad consequences, a temperate and natural gratification, under proper circumstances, is attended with good, besides the mere attendant pleasure, which alone is enough to recommend such gratification. I admit that human beings might be so constituted that if they had no reproductive instinct to gratify, they might enjoy health; but being constituted as they are, this instinct cannot be mortified with impunity. It is a fact universally admitted, that unmarried females do not enjoy so much good health and attain to so great an age as the married; notwithstanding that the latter are subject to the diseases and pains incident to child-bearing. A temperate gratification promotes the secretions, and the appetite for food; calms the restless passions; induces pleasant sleep; awakens social feeling; and adds a zest to life which makes one conscious that life is worth preserving.
