These facts show clearly that there is a vital relation between the sexual nature and the social nature. If developed and kept normal, they will contribute much to the enjoyment of life. Like all great blessings they have their dangers. Whatever, in the social relations of young men and women, leads to the excitement of the sexual instinct means danger, temptations and ofttimes social disaster. Almost all men have either inherited or acquired a strong tendency toward easy sexual excitement. Most young men are ignorant of their weakness and the laws of sexual excitement. In these regards the birds and lower animals are much truer to nature than is, degenerate, man. Among them the sexual exciting relations, preparatory to the reproductive act, are never indulged in by the male except during the mating season. The lower animals never violate these laws of normal sexual excitement. =A pernicious custom.=--Many young men, ignorant of these laws, prompted by an over-developed sexual condition, have the habit of pinching the arms of girls, patting their cheeks and chins, squeezing their hands, playing with the hair, hugging and kissing them, and other indiscreet and dangerous habits. These relations are known by modern society as “spooning.” It is seriously common. It is more dangerous to physical, sexual, mental and moral health than the secret sin or prostitution. It is the kindergarten for both. Few young people would ever fall were it not for these pernicious and foolish customs. You should treat every young lady as you would have other young men treat your sister. You should have a correct knowledge of these laws and by an intelligent choice and a manly, strong purpose, refuse ever to engage with young women in any social relation that would endanger your honor or their virtue. =Friendship and love.=--For a number of years you may for social reasons wish to call occasionally on one or more girls for whom you will entertain only thoughts of friendship. However, friendship occasionally assumes a more serious turn and is transformed mysteriously into love. If this love is natural, prompted by your paternal nature, approved by your reason and judgment, no mistake will be made. Love can be blinded by lust, paralyzed by wealth and hypnotized by beauty and in either event, marriage would be a failure. =A good wife is a helpmate.=--If a young man has perfect control of his sex nature, I would not advise marriage before he is twenty-three or four. If he has a few hundred dollars ahead, a good education, or a good paying position, has good health and has found the girl of his choice, he should not postpone marriage until he has accumulated more. A good wife is a helpmate.
