The natural secretions of the male organs also become morbid in licentious men, developing into blennorrhagia, or purulent gonorrhœa, and thus the danger of promiscuity is intensified. Neither is it possible, when such injurious practices are allowed, to cleanse or disinfect the female parts as if they were a plane surface. The woman’s structure is designed for the passage of a child’s head. It is consequently composed of immensely distensible or elastic tissue, forming folds or rugæ, which may retain diseased products. It is also abundantly supplied with active secretory and absorbent glands, whose action may become unhealthy. The special danger of specific disease also arising from the congress of different races is a well-known fact. The alarming epidemic of venereal disease, which spread like the plague through Europe in the fifteenth century, was brought from America by the licentious conquerors of Peru. This gravest form of racial injury is now being emphasized by the contrast between the condition of our white and coloured troops in India. Although medical investigation has failed to determine precisely the originating cause of the specific virus which produces the form of venereal disease named syphilis, yet it is always connected more or less directly with promiscuous intercourse, especially with the advance of armies.[10] We know, however, that morbid changes may take place in the natural secretions of the male and female organs under impure sexual intercourse, leading to advanced forms of degeneration in the various results of gonorrhœa, producing, particularly when the epidermis is abraded, sores, ulcers, etc. And the poison of diseased secretion is thus conveyed from one to the other partner in vice. Nor can the presence of infectivity, once acquired, be detected by inspection; and no infected immoral person, still carrying on impure sexual relations, can ever be pronounced healthy or ‘sound’ by means of examination or ocular investigation. Neither can the absence of the so-called venereal germ gonococcus be relied on as proving health. Its specific significance is denied by many competent investigators, and it is absent in some of the worst forms of disease. ‘Mediate contagion’ is also an important and well-established medical fact. Thus a famous French harlot, called ‘Casse-noix,’ presented none of the grosser signs of venereal disease, yet continued to infect the men who resorted to her. When to the difficulty of pronouncing the parts with their secretions healthy, is added the existence of uncleanliness, of drunkenness, etc., in either party, the danger of these promiscuous relations is evident.
