Flirting is not confined to young men and women. The contagion extends to little boys and girls, whose heads ought to be as empty of all thoughts of … - John Harvey Kellogg

From earliest infancy all of those influences and agencies which cultivate chastity should be brought into active exercise. These we need not repeat here, having previously dwelt upon them so fully. The reader is recommended to re-peruse the portion of the work devoted to this subject, in connection with the present section. If parents have themselves indulged in this vice, they should use special care that all of the generative and gestative influences brought to bear upon their children are the purest possible, so that they may no inherit a predisposition to sin in this direction. Special care should be exercised to avoid corrupt servants and associates. Every servant not known to be pure should be suspected until proof of innocence has been established. They should be especially instructed of the evil arising from manipulation of the genitals even in infants, as they may do immense harm through simple ignorance.

”It is a remarkable fact, in this connection, that the female of these animals will allow the approaches of the male only during and immediately after the oestral period; that is, just when the egg is recently discharged, and ready for impregnation. At other times, when sexual intercourse would be necessarily fruitless, the instinct of the animal leads her to avoid it; and the concourse of the sexes is accordingly made to correspond in time with the maturity of the egg and its aptitude for fecundation.” “The egg, immediately upon its discharge from the ovary, is rady for impregnation. If sexual intercourse happens to take place about that time, the egg an the spermatic fluid meet in some part of the female generative passages, and fecundation is accomplished. . . . If, on the other hand, coitus do not take place, the egg passes down to the uterus unimpregnated, loses its vitality after a short time, and is finally carried away with the uterine secretions.” “It is easily understood, therefore, why sexual intercourse should be more liable to be followed by pregnancy when it occurs about the menstrual epoch than at other times . . . Before its discharge, the egg is immature, and unprepared for impregnation; and after the menstrual period has passé, it gradually loses its freshness and vitality.

Are Occasional Emissions Necessary or Harmless?-That an individual may suffer for years an involuntary seminal loss as frequently as once a month without apparently suffering very great injury, seems to be a settled fact with physicians of extensive experience, and is well confirmed by observation ; yet there are those who suffer severely from losses no more frequent than this. But when seminal losses occur more frequently than once a month, they will certainly ultimate in great injury, even though immediate ill effects are not noticed, as in exceptional cases they may not be. If argument is necessary to sustain this position, as it hardly seems to be, we would refer to the fact that seminal losses do not occur in those who are, and always have been, continent both mentally and physically, when such rare individuals can be found. They occur the most rarely in those who the most nearly approach the standard of perfect chastity ; so that whenever they occur, they may be taken as evidence of some form of sexual excess. This fact clearly shows that losses of this kind are not natural.
