A full enjoyment of sexual intercourse depends as much upon the proper time chosen, the condition of the parties, and their mutual sympathies, as upon the fact that they are really persons of the opposite sex. It should not be indulged in except when there is a natural desire and a vigorous impulse. It should be avoided whenever it tends to produce a depression of spirits, or the least debility. It should never be indulged in during intoxication, or where the sexual organs of either party are diseased or out of order. It ought to be entirely abstained from during six or seven days after the commencement of the female monthly turn, and for one month after child-birth. It would be better, for both mother and child, if no sexual intercourse was indulged in during the whole period of suckling her infant, but as that abstinence is not to be expected from ordinary men, I advise as little connection as possible during that time. And should connection with a suckling mother prematurely bring on her menses, (as it sometimes does,) she must immediately wean her child. Female prostitutes never enjoy their sexual connections with strangers—they are mere passive instruments—while the male only relieves himself of a superabundance of Semen. Too frequent intercourse is quite as unnatural; those who practice it rob themselves of more than half the pleasure they seek. A man in robust health who has refrained from sexual pleasures, may, it is true, enjoy such intercourse once in twenty-four hours for several days together; but he could not attain the full enjoyment from one female. He must then rest. I speak of the highest degree of sexual pleasures. Many newly married couples give no limit to their indulgences; and it is to such that I say, you deny yourselves of the real pleasures of married life. A little philosophy, and some experiments on the hints given, would render the married state a state of more refined pleasures than it now presents to a large class of mankind. The particular food which is calculated to stimulate the sexual organs is shell-fish, or sea fish of any kind, and turtle, as these generally contain phosphorus. Among vegetables may be mentioned celery, parsnips, onions, peppers, asparagus, tomatoes, Lima beans, &c. Mushrooms and truffles are a stimulant, as is also mint, sage, pennyroyal, thyme, and spices of all kinds, especially pepper and nutmeg. Canvas-back Duck, in proper season, is of excellent stimulating qualities; and for puddings, sago, tapioca and arrowroot. For drinks take porter and strong beer, wines, or coffee. Spirits are too exhilerating, and cause a reaction. HOW TO AVOID CHILD-GETTING.
