What have we to say regarding the voluptuous sensation in children? It is extremely difficult to form clear ideas about this matter, for the sources of fallacy previously described (p. 5 _et seq._) are here markedly in operation; above all, in the case of little children, the voluptuous sensation, purely subjective in character, is extraordinarily difficult to recognise objectively. This much, however, may be said. It appears to me to be beyond question that in childhood, and even in very early childhood, a sensation may sometimes be excited of the same kind as the voluptuous sensation of adult life. None the less, we must be careful not to assume too readily, in any particular case, that such a sensation has actually been experienced. Certain oscillatory movements on the part of infants and other small children have frequently been regarded as an indication of the practice of masturbation, and of the occurrence of voluptuous sensations; but in my opinion that view is to a large extent erroneous. Such movements may be no more than the expression of a general sense of well-being, without having anything whatever to do with the sexual life or with the specific voluptuous sensation. Doubtless the voluptuous sensation may be experienced by very small children, and even by infants. When we see a child lying with moist, widely-opened eyes, and exhibiting all the other signs of sexual excitement, such as we are accustomed to observe in adults, we are justified in assuming that the child is experiencing a voluptuous sensation. But what is usually wanting in such cases, at any rate in young children, is the voluptuous acme which in adults occurs in association with the act of ejaculation. Cases have also been occasionally reported to me in which, even in infancy, a voluptuous acme has occurred; and still more frequently I have been told this in respect of somewhat older children, for example, at ages of seven or eight years. I believe, however, that this voluptuous acme is, at any rate in children, much less common than the equable voluptuous sensation which can be aroused by all kinds of manipulations and stimulations of the peripheral genital organs, and more especially of the glans, the penis, the clitoris, and the labia minora. The older the child, the more frequently is the voluptuous acme attained; in our own climate, during the last years of the second period of childhood, this occurs comparatively often; the voluptuous acme does not last so long as in sexually mature individuals, but is in other respects described in identical terms. It is experienced simultaneously with the occurrence of the rhythmical muscular contractions which have previously been described. It is possible, as I suggested before, that in such cases the ejaculation of a certain quantity of glandular secretion always occurs, although, as I have also explained, this secretion may sometimes be too small in quantity to be actually expelled from the urethra by the
