In so far as in what has gone before I have described the individual processes, there appear to be no important differences between the boy and the girl, over and above those dependent upon the different structure of the genital organs in the respective sexes. But one notable difference must now be indicated. Just as in adult life in the female sex sexual anaesthesia is very frequently observed, so that in coitus the specific voluptuous sensation is wanting, and indeed often enough the impulse to coitus itself is actually in abeyance (whereas in men the sexual impulse and sexual pleasure are very rarely absent), so also in the case of children a similar difference between the sexes is conspicuous. In female children the peripheral processes of the sexual impulse are, comparatively speaking, far less active than in the case of males. Thus it happens that, although in the girl the phenomena of the contrectation impulses are hardly, if at all, less conspicuous than they are in the boy, and appear at as early an age in the former as they do in the latter, yet in respect of detumescence there is an important distinction between girls and boys. A girl who has fallen in love with a boy will be greatly interested in all his doings, and will gladly embrace and even kiss him; but she will be far less disposed to proceed to actions in which the genital organs play a part than would a boy with a like affection for a girl. The same rule holds good when, in the undifferentiated stage of the sexual impulse, homosexual sentiments and practices ensue. In such cases, when girls are concerned, caresses of all kinds will follow, but the genital organs will in all probability not be involved; whereas in the case of an analogous fondness between two boys, manipulation of the genital organs is very likely to occur. Homosexual intimacies between girls are far more often platonic than similar intimacies between boys.
