Similarly, it will be far easier in the case of children to observe peripheral processes in the genital organs than it is to make such observations in adults. Thus, even in the case of infants in arms, but more often in the case of boys who are somewhat older, the mother or the nurse may be surprised to observe erections when the boy is undressed for his bath or some other reason, or when he has kicked off the bedclothes at night. In other cases the child may be seen handling his genital organs, either openly or beneath his clothing. Often, in the absence of manual stimulation, the child adopts some other means of stimulating his genital organs. Thus, in girls the legs will be crossed, and the thighs rubbed lightly each against the other. In other cases, both in boys and in girls, the child will lean against a piece of furniture in what appears to be a perfectly innocent manner; but in reality pressure is being exercised on the genital organs, it may be by the corner of a table, it may be by the back of a chair; and then the stimulus is strengthened by various movements. In some such way children will effect masturbatory stimulation and obtain sexual gratification, in the presence, not only of their mother, but in that of quite a number of other persons. Guttceit[78] reports the case of a woman who squatted down so that her bare heel came into contact with the genitals, and she then masturbated by rubbing the two parts together. I myself have known the case of a young girl who sat with her legs beneath her, and masturbated with the boot she was wearing. In many instances we are enabled, by watching the child's movements, to ascertain with such certainty what it is doing, that no confirmatory evidence is needed. We notice, especially, that when the orgasm is approaching, the movements change in character and rhythm. The eyes become bright, and the face assumes an excited and voluptuous expression. This may be observed even in infants in arms. Townsend[79] reports the case of an infant, eight months old, "who would cross her right thigh over the left, close her eyes and clench her fists; after a minute or two there would be complete relaxation, with sweating and redness of face; this would occur about once a week or oftener; the child was quite healthy, with no abnormal condition of the genital organs."
