Both the tremendously and the ultra-virile tend to excel in physique and comeliness. Some athletes, however, are only mildly virile. “Virility” refers only to sexual power. More than the ordinary erotic ardor, however, usually goes hand in hand with [Sidenote: _The Mildly Virile._] _brawn_, just as intellectual tastes and spirituality do with _brain_. With the evolution of the race in culture, erotic ardor, together with the animal side of man’s nature in general, is declining. The goal for which the race is headed is the minimum of sexual consciousness, coitus for procreation only, just enough offspring to keep the number of the human race on earth stationary, lengthened life, and ever increasing expansion of the intellectual in man at the expense of the physical. With this evolution, the proportion of sterile bisexuals will also increase. The fighting forces of a nation are almost entirely made up of the two more virile classes, although together constituting only about twenty-five per cent of the total manhood of civilized nations. It is dangerous for the world’s peace when these two classes get control of a great nation’s government. Of the five classes of males being described, these two alone love war and seek occasion for it. (3) The MILDLY VIRILE constitute, among so-called “Christian” nations, about seventy-five per cent of all males.[3] Only on rare occasions do thoughts [Sidenote: _Natural Monogamy._] about sexual congress enter their minds. That is, if married, they desire it only about once a fortnight or so, and up to the date of marriage, the incentive is so weak that they never gratify it. Thus up to the bridal night, this class three have usually been as chaste as their better halves. They have usually never indulged even in masturbation, while the generality of classes one and two have indulged frequently from around the age of ten to the period in which opportunities _cum femina_ or _cum androgyna_ become plentiful. In the mildly virile man’s ignorance of the force of sex in classes one and two, however, he has been known to be obsessed with the delusion that sex in himself is strongly developed. The mildly virile always marry, although a few postpone it until much past thirty. Subsequently they have at most only negligible desires to drink water at a strange cistern. They are content to go to their graves having been absolutely faithful to the lawful wife, or several successive ones, that God gave them. Divorce is almost unknown, since its cause, in nearly every case, is _de facto_ polygamy in the husband, or his excessive demands on the frigid wife—two faults absent from the psyche of the mildly virile.
