The social sexual position of woman suffers most at the present day from the mature age at which under existing social conditions men are alone able to marry and from the ever-increasing number of cases of venereal infection. In both these directions social science and medical skill must work hand in hand for the amelioration of the sexual life of woman. On the twentieth century falls the duty of furnishing a solution for these problems. Contesting voices are heard on all sides. _Tolstoi’s_ rigid demand for complete sexual abstinence, the exhortation of the professors of the German universities to their students in favor of moral purity, the associations for the official prevention of venereal diseases, the agitation among young men in favor of abstinence from sexual intercourse before marriage, finally, the clamorous voices of the supporters of women’s rights—all these are influences within the sphere of sexual morality, which must lead slowly but surely to extensive social changes in the sexual life of women. The discussion of the sexual life of woman, which for many centuries was concealed by a thick veil from the eyes of the profane, or was viewed only through the frosted glass of poetical metaphor, has in recent times assumed a quite revolting character. Not only have the acquired liberties and the social aims of the present day a tendency to give to women in general a freer and higher position, to emancipate them from the bonds in which owing to the conditions of family life they have so long been shackled, but some members of the women’s rights party go even farther, and demand for women greater freedom in the sphere of sexual activity.
