Marriage is the most dangerous social institution!
Ouch! Well, guess whom this is from, without Googling?
At present marriage is easily the most dangerous of all our social institutions. This is partly due to the colossal ignorance of the public in regard to sex, and partly due to the fact that marriage is mainly controlled by lawyers and priests instead of by women and doctors. The legal and religious aspects of marriage are not the primary ones. A marriage may be legal—and miserable; religious—and diseased. The law pays no heed to the suitability of the partners, and the Church takes no regard for their health. Nevertheless, the basis of marriage is obviously mating, or sexual intercourse. Without that there is no marriage, and with it come not merely health and happiness but life itself. Cut out sexual intercourse, and society becomes extinct in one generation. Every generation must, of necessity, pass through the bodies of its women; there is no other way of obtaining entry into the world. Hence, it is clearly the duty of women to understand precisely the processes involved, from beginning to end.
With the lower animals sexual intercourse is desired only seasonally, and only for the purpose of reproduction. With the higher animals—man and women—sexual intercourse is desired more or less continuously throughout adult life, and desired much more for romantic than for reproductive considerations—that is, for the sake of health and happiness rather than for the sake of procreation only. A few women, and still fewer men, have no sexual desires. To them sexual abstinence seems more natural than sexual satisfaction. But for the majority of mankind and womankind—for all normally healthy men and women—there is this continuous desire to be happily mated.
It's interesting from any viewpoint how she gets quickly to her views and ideas on certain things. That's the first two paragraphs of the introduction above. The first five sentences, and especially the fourth, are quite telling in this regard.
