Amongst the better classes of townspeople such hygienic regulations and educational measures are in common employment that young girls during the years of development usually receive reasonable care and attention—but very frequently, intercourse with older girls, association with young men, visits to theatres, evening-parties, and balls, and the perusal of stimulating literature, form unfavorable features of urban life which exercise their inevitable effects in the sexual sphere. In some cases, fortunately sufficiently rare, the stimulation of the sexual impulse and the longing for its satisfaction are so intense, that a kind of _demi-vierge_ is brought into being, a young woman who is concerned only to preserve the physical token of virginity, but whose thoughts and fancies are anything but maidenly. It is to be feared that in consequence of the excessive freedom in education and the emancipated independence of feminine youth, these “half-virgins” are increasing both in number and in intensity, a fact which cannot fail to increase also the number of sexual maladies and perversions. _Anatomical Changes in the Female Genital Organs in the Period of the Menarche._ The female reproductive organs, which in childhood were in a comparatively quiescent state, now become powerfully active, as is witnessed by the changes that occur in the external genitals. The soft, hairless vulva of the child becomes enlarged at the time of the menarche by the deposit of fat, and its substance becomes tough and elastic. Some time before puberty, fine, pale hairs make their appearance here and there, but not until puberty does the hairy covering of the pubic region become more or less thick. The growth of the denser pubic hair begins with the appearance of hairs along the middle of the mons Veneris and at the margins of the labia majora. Early sexual development is commonly indicated by an early and thick growth of the pubic hair. In the virgin this hair is smoother and less curly than in the later course of the sexual life. In certain tribes of negroes it is the custom for the young unmarried girls to shave off the pubic hair, which is not allowed to grow freely until after marriage. In some of the tribes of South Sea Islanders it is customary at puberty to tattoo the external genitals and the surrounding skin.
