Such a girl may succeed in persuading herself that this motive is the exclusive cause of her interest in the boy. A similar combination of educational and sexual motives is, moreover, often encountered in the case of homosexual sentiments. The child's sexual inclination may manifest itself in many different ways. It seeks every opportunity of seeing, of being in close proximity to, of touching, and of kissing the beloved person. Thus, many a boy takes part in the common sports, solely because the girl whom he loves is one of the players. Sanford Bell mentions numerous games in which children find pleasure chiefly for the reason that kissing plays a principal part in them. For kissing is one of the leading manifestations of sexual desire; and another is the wish for close proximity to and for embracing the beloved person. A mother who kept a close watch on her eight-year-old daughter told me that when in play a boy of ten pressed close up against the girl; they kissed one another somewhat passionately, and the boy broke out in the naive utterance, "You don't know how fond I am of you; I do love you so." Not infrequently, indeed, children are really troublesome to adults in their desire for close physical contact. I have known instances in which young women or girls have been intolerably annoyed by boys eight or nine years of age, who have continually followed them about and pressed up against them; this has gone on for a long time without those concerned recognising the sexual foundation of such conduct. Love on the part of children almost invariably gives rise to the desire for physical contact of some kind. Of course, other manifestations also occur. Besides the contemplation of the beloved person, contemplation of his or her picture plays a notable part. A sexual motive occasionally underlies the wrestling so common among boys--in such cases it is the manifestation of a desire for intimate physical contact with the beloved boy. According to Sanford Bell, a boy and a girl may also wrestle with one another with the same end in view of attaining intimate contact; and he states that children lift one another with the same object. Moreover, children are induced to wrestle by sexual motives of a somewhat different character; the wish is operative to be overcome by, or, it may be, to overcome, the beloved boy. Herein we see displayed very clearly those sexual feelings known to us in adults under the names of masochism and sadism; the same feelings are occasionally observed also in childhood; in some cases as manifestations of the undifferentiated sexual impulse, in others as manifestations of developing sexual perversions.
