Frigidity as an agent in marriage may be considered from two points of view: the offspring and the husband. The offspring is not affected by the mother's frigidity. A very frigid woman, if the frigidity is not due to serious organic causes, may have very healthy children and make an excellent mother. As far as the husband is concerned, it will depend a good deal on the degree of frigidity. If the woman is merely cold, and, while herself not enjoying the act, raises no objection to it, then it cannot be considered a bar to marriage. In fact many men, themselves not overstrong sexually, are praying for somewhat frigid wives. (It must be stated, however, that to some husbands relations with frigid and non-participating wives are extremely distasteful.) But when the frigidity is of such a degree that it amounts to a strong physical aversion to the act, it should be considered a bar to marriage. Such frigidity is often the cause of a disrupted home, often leads to divorce and is legally considered a sufficient cause for divorce or for the annulment of marriage, the same as impotence in the man is. =Excessive Libido in Men= We have seen that sexual impotence is a dysgenic factor and if complete and incurable should constitute a barrier to marriage. The opposite condition is that of excessive libido. Libido is the desire for the opposite sex. A proper amount of libido is normal and desirable. A lack of libido is abnormal. And an excess of libido is also abnormal. But a good many men are possessed of an excess of libido; it is either congenital or _acquired_. Some men torture their wives "to death," not literally but figuratively. Harboring the prevailing idea that a wife has no rights in this respect, that her body is not her own, that she must always hold herself ready to satisfy his abnormal desires, such a husband exercises his marital rights without consideration for the physical condition or the mental feelings of his partner. Some husbands demand that their wives satisfy them _daily_ from one to five or more times a day. Some wives who happen to be possessed of an equally strong libido do not mind these excessive demands (though in time they are almost sure to feel the evil effects), but if the wife possesses only a moderate amount of sexuality and if she is too weak in body and in will-power to resist her lord and master's demands, her health is often ruined and she becomes a wreck. (Complete abstinence and excessive indulgence often have the same evil end-results.) Some men "kill" four or five women before the fury of their libido is at last moderated. Of course, it is hard to find out a man's libido beforehand. But if a delicate girl or a woman of moderate sexuality has reasons to suspect that a man is possessed of an abnormally excessive libido, she would do well to think twice before taking the often irretrievable step.
