The outer sides of the labia majora are covered with hair, and on the inner sides, which are smooth and moist, but are not true mucous membrane, there are a few sweat glands and numerous large sebaceous glands. Bergh considers that there is little or no hair on the inner sides of the labia majora, but Lamb states that careful examination shows that from one- to two-thirds of the inner surface in adult women show hairs like those of the external surface. In brunettes and women of dark races this surface is pigmented; in dark races it is usually a slate gray. From an examination of 2200 young Danish prostitutes Bergh has found that there are two main varieties in the shape of the labia majora, with transitional forms. In the first and most frequent form the labia tend to be less marked and more effaced and separated at the upper and anterior part, often being lost in the sides of the mons and presenting a fissure which is broader in its upper part and showing the inner lips more or less bare. In the second form the labia are thicker and more outstanding and the inner edges lie in contact throughout their whole length, showing the _rima pudendi_ as a long narrow fissure. Whatever the form, the labia close more tightly together in virgins and in young individuals generally than in the deflowered and the elderly. In children, as Martineau pointed out, the vulva appears to look directly forward and the clitoris and urinary meatus easily appear, while in adult women, and especially after attempts at coitus have been made, the vulva appears directed more below and behind, and the clitoris and meatus more covered by the labia majora; so that the child urinates forward, while the adult woman is usually able to urinate almost directly downwards in the erect position, though in some cases (as may occasionally be observed in the street) she can only do so when bending slightly forwards. This difference in the direction of the stream formerly furnished one of the methods of diagnosing virginity, an uncertain one, since the difference is largely due to age and individual variation. The main factor in the position and aspect of the vulva is pelvic inclination. (See Havelock Ellis, _Man and Woman_, fourth edition, p. 64; Stratz, _Die Schönheit des Weiblichen Körpers_, Chapter XII.) In the European woman, according to Stratz, a considerable degree of pelvic inclination is essential to beauty, concealing all but the anterior third of the vulva. In negresses and other women of lower race the vulva, however, usually lies further back, being more conspicuous from behind than in European women; in this respect lower races resemble the apes. Those women of dark race, therefore, whose modesty is focused behind rather than in front thus have sound anatomical considerations on their side.
