A classical description of her first nocturnal orgasm is given by Madame Roland in her Mémoires Particuliers,[43] written during the last months of her life in prison in Paris at the time of the Terror. She menstruated for the first time, she informs us, soon after she had been partially enlightened regarding sexual matters by her grandmother. Even before menstruation began, she had experienced sexual excitement in dreams. "I had sometimes been awakened from a deep sleep in a most remarkable manner. My imagination played no part in what occurred; it was occupied with far more serious matters, and my tender conscience was far too strictly on guard against the deliberate pursuit of pleasure for me to make any attempt to dwell in imagination on what I regarded as a forbidden province of thought. But an extraordinary outbreak awakened my senses from their quiet slumber, and, my constitution being a very vigorous one, a process whose nature and cause were equally unknown to me made its appearance spontaneously. The first result of this experience was the onset of great mental anguish; I had learned from my 'Philothea'[44] that it was forbidden to enjoy any bodily pleasure, except in lawful wedlock; this teaching recurred to my mind; the sensations I had experienced could certainly be described as pleasurable; I had, therefore, committed a sin, and, indeed, a sin of the most shameful and grievous character, because it was the sin most of all displeasing to the Lamb without blemish and without spot. Great disturbance of mind, prayers and penances; how could I avoid a repetition of the offence? for I had not foreseen it in any way, but in the moment of the experience I had taken no trouble to prevent it. My watchfulness became extreme; I noticed that when lying in certain positions I was more exposed to the danger, and I avoided these positions with anxious conscientiousness. My uneasiness became so great that ultimately I came to wake up before the catastrophe. When unable to prevent it, I would jump out of bed, and, notwithstanding the cold of winter, stand bare-footed on the polished floor, crossing my arms, and praying earnestly to God to guard me from the snares of Satan." She goes on to describe her subsequent attempts to mortify the flesh by means of fasting.

I have hitherto described the individual sexual processes which are observed during childhood, I have already explained that in some, one process, in some, another process, is alone present, or, at any rate, preponderates. For instance, a girl may be sexually attracted towards a boy without the genital organs playing any conscious part in the attraction. But the converse may also occur. Moreover, the strength of the sexual feeling is subject to extensive individual variations. In some children the sexual impulse is so powerful that scandalous misconduct can hardly be avoided; on the other hand, we see cases in which the sexual impulse manifests itself at the normal age, but is so weak that it can scarcely be said to play any important part in the consciousness of the child. This is true of both components of the sexual impulse, of the phenomena of contrectation, no less than of those of detumescence. Formerly it was very generally believed that in sexually perverse persons the sexual sensations awakened unusually early in life. There is no foundation for this view. Normal sexual sensations can be detected very early in childhood. The existence of these was ignored, simply because the study of the normal was neglected for the study of the perverse. Moreover, the strength of the sexual sensations has no necessary association with the existence of perversions; these latter sometimes occur without being particularly strong. On the other hand, qualitatively normal sexual sensations may be associated with sexual hyperæsthesia, and they may attain a notable strength even during childhood.

In the third chapter I showed that in childhood the sexes are differentiated both physically and mentally, altogether apart from the genital organs and the sexual impulse; and I pointed out that games in particular afforded indications of mental sexual differentiation. Many games, indeed, may even be regarded as direct manifestations of the sexual impulse, and I must therefore now return to the consideration of this topic; but I shall confine myself to certain phenomena observable in the animal world, since the games of animals are, in this connexion, so much simpler than those of children. Play constitutes a major part of the activities of young animals; think, for instance, of a kitten playing with a hanging tassel or with a ball, of puppies chasing one another, and of young birds playing with fluttering wings. The games of young animals often exhibit the character of love-games, and are in that case sexually differentiated. Various authors, and especially Brehm, have recorded numerous examples of this; I give here a few instances, quoted from Groos.[45] The young male, even before its testicles have developed, woos the female by movements, song, or other characteristic sounds. The female, also sexually immature, responds coquettishly to these advances of the male. Song, which Brehm regards as a sign of the awakening of love, makes its appearance at an age when the animal is still unfitted for the reproductive act.

"Young magpies (Corvus pica) address one another in September, and often in August and in October, in consecutive clucking notes, and in this way make exactly the same kind of noise that they are always heard making in early spring just before the pairing season. The young male green woodpecker (Picus viridicanus) sings in September as beautifully as in April, as I have myself heard more than once; the young great spotted woodpecker (Picus major) may even be heard at times in autumn, just as in spring, making his characteristic tapping sound as he explores hard branches in search of insects. Both varieties of creeper begin to sing before they have changed their youthful plumage; their song closely resembles that of the adult birds in spring, but the note is somewhat shorter and weaker. Similarly, both the German varieties of crossbill commonly begin to sing before losing the plumage characteristic of youth. Young house-sparrows and hedge-sparrows not only chatter and swear at one another like the full-grown birds at pairing time, but also like the latter the young birds distend their throats, let their wings droop, peck at one another, and in fact behave as exactly as they will next spring when fully grown. Young linnets also begin to sing before losing their youthful plumage, learn to sing well during the moulting season, and often continue to warble right on into the winter; in a mild winter young linnets will sing just as well as old ones. The young woodlark begins to sing as soon as its first moulting is nearly over, and not only does this when perching, but flies aloft like the adult bird in the spring-time, and soars for a long time, singing continually. Titmice all sing when still quite young, but more especially the large crested titmouse and the marsh titmouse; the notes of the young marsh titmouse are precisely similar to those with which in spring the adult bird sings to his mate; and as regards the crested titmouse, in October 1821, I observed a young male bird making advances of a most marked character to a young hen, whilst the hen drooped its wings and spread out its tail—in short, these two young birds were behaving exactly as do the full-grown birds before pairing in the spring. The young cock starling conducts itself precisely as if it wished to pair. At the beginning of September, as soon as moulting is completed, this bird returns to its birthplace, apparently in order to take possession of the nest. It perches on the tree-top, just like the full-grown bird in March, and sings almost for the whole morning. While still perching, it flaps its wings, quarrels with and chases other young starlings; sometimes it even creeps into the hollow tree or other hiding-place containing the nest in which it was hatched. The yellow wagtail sings while still in its youthful plumage, and the young birds chase one another about while in this condition; during and immediately after the first moulting, these birds produce peculiar trilling notes, identical with those with which in April the cock bird salutes his mate, and they may also be seen in the remarkable fluttering flight characteristic of many birds in the pairing season. The grey wood wren begins to sing before the first moulting, but sings more powerfully during and after moulting, right on into the month of October, singing like a full-grown bird. At the same time this bird twists the body from side to side, and moves the tail to and fro; it quarrels also with birds of its own species, and quarrels, too, with other birds, sometimes with birds as much as four times its own size. In August and September young mountain fowl and heath fowl utter love calls to each other, not, indeed, so loudly as those of the adult birds, nor in association with the characteristic movements of the body made by these latter in the spring-time, but still unmistakable love calls.... According to Hudson, many kinds of American woodpecker carry on a kind of duet, and they practise this artistic performance from the very earliest youth. On meeting, the male and female, standing close together, and facing each other, utter their clear ringing concert, one emitting loud single measured notes, while the notes of its fellow are rapid, rhythmical triplets; their voices have a joyous character, and seem to accord, thus producing a kind of harmony. This manner of singing is perhaps most perfect in the oven-bird (Furnarius), and it is very curious that the young birds, when only partially fledged, are constantly heard in the nest or oven apparently practising these duets in the intervals when the parents are absent; single measured notes, triplets, and long concluding trills are all repeated with wonderful fidelity, and in character these notes are utterly unlike the hunger cry, which is like that of other fledglings."

In such cases as those just enumerated, actual copulation is not effected; but animals still sexually immature may perform coitus-like acts, and Groos's work contains observations of these made by Seitz and others. Seitz saw an antelope six weeks old making copulatory movements. In young dogs such movements may often be observed, also in young stallions and young bulls.

The view that in such cases the movements are imitative merely is untenable, for young animals which have never had any opportunity of watching the physical manifestations of love in older ones, will nevertheless themselves exhibit such manifestations. At most it remains open to dispute whether in these cases it is still permissible to speak of love-games, as do Groos and others, or whether we should not rather speak simply of manifestations of the activity of the sexual impulse. But the dispute does not involve differences of opinion regarding matters of fact; it is purely terminological. For, in the first place, Groos himself, who regards the games of childhood as a form of training, suitable to the nature of the individual, for its subsequent activities, recognises that games are sexually differentiated. He believes that we have to do, not, as some think, with imitative processes, but with preliminary practice, subserving the purposes of self-development; and he considers that girls naturally turn to games adapted to train them for their subsequent profession of motherhood, whilst boys incline to games corresponding to their predestined activity as men. Even if we accept this theory of Groos, we are compelled to recognise a sexual element in the games of youthful animals. In addition, however, we must note the fact that Groos gives a wider extension to the concept of play than other writers, and that he regards as love-games processes which others might perhaps describe as sexual manifestations. According to Groos, caressing contact is to be regarded as playful when, in the serious intercourse between the sexes, such contact appears to be merely a preliminary activity rather than an end in itself. Here two cases are possible: in one the carrying out of the instinctive activity to its real end is prevented by incapacity or by ignorance; in the other, it is prevented by a deliberate exercise of will. The former occurs in children; the latter, often enough in adults. Whatever view we hold regarding this matter, the sexually differentiated love-games of young animals must be regarded as a manifestation of the sexual life. None the less, in sexually immature animals, just as in the case of children, sexual differentiation is not always so marked as it is in adults; and it may happen that the sexes may exchange their rôles. Cases observed by Seitz have been published by Groos and also by myself.[46] I have myself watched a young cow which repeatedly attempted to mount another young cow; I have also on several occasions seen young bitches attempt to cover dogs. To this part of our subject belongs the observation of Exner, that when dogs are playing wildly with one another one hardly ever sees a bitch among them. But if an exception should occur, the bitch is usually a young one. In animals, sexual differentiation is not complete until sexual maturity is attained, and the same is true of the human species, although, as I have shown above, children already manifest sexual differentiation in their games, their inclinations, and their general conduct.

I have thought it desirable to refer to the play of animals in this place, as well as to treat of the subject in its direct relationship to the sexual impulse. What is true of play is true also of the other interests and inclinations of the child, many of which are also associated with the sexual life; these have been described earlier, so that here I need merely allude to the matter in passing.

Hitherto I have described the sexual life of the child in so far as it is the subject of direct observation or can be recalled to memory. But it was explained at the outset that there is still another way of gaining clear knowledge of the subject, namely, by experiment; and it was shown that castration may be regarded as such an experiment. Although the reproductive capacity of the male is not developed prior to the formation of spermatozoa in the testicles, nevertheless we learn from the effects of castration that the testicles exhibit important functional activity much earlier in life. This fact was long overlooked, and its importance is even to-day largely underestimated, because we have been accustomed to regard the provision of an external secretion as the only function of the testicle. But it is now firmly established that these glands exercise influence in other ways. We know that bodily and mental development are affected by the removal of the testicles; and that the influence is greater the earlier in life the castration takes place. A number of secondary sexual characters remain undeveloped. The beard does not grow; in many instances a thick panniculus adiposus is formed; there are changes in the growth of the bones; the voice remains a soprano; and the other reproductive organs are imperfectly developed, the penis and the prostate remaining comparatively small An early castration does not, of course, result in the obliteration of all differences between the male and the female; we must rather say that a part only of the typical differential characters of sex remain undeveloped. The earlier assumption, that the secretion of semen competent to effect fertilisation influenced the development of the secondary sexual characters, has of late been more and more generally abandoned. Many considerations tell against such a theory, more especially a comparison of the three following facts. First, if castration is not effected until after the formation of spermatozoa has already begun, the familiar results of this operation are either entirely wanting, or else appear to a small extent only, and are limited to a small number of the secondary sexual characters. Secondly, the results of castration are most marked when the operation is performed in early childhood. Thirdly, when castration is effected in the later years of childhood, but before the secretion of fertilising semen has taken place, the results are intermediate in degree, being much less marked than in the second class of cases, but more extensive than in the first. If the secretion of a fertilising semen were the principal factor in the development of the secondary sexual characters, we should expect the results of castration to be the same whether the operation were performed early in childhood or late so long as it was done before any spermatozoa had been formed.

The secondary sexual characters are, therefore, independent of the formation of spermatozoa, and the appearance of these characters must depend upon other processes, occurring much earlier in life. Thus, in persons who were castrated in the eighth or ninth year of life, we note the presence of definite secondary sexual characters, which are, indeed, less strongly developed than in normal persons, but which do not appear at all when the castration has been effected at a still earlier age. The varying views of different authors regarding the influence of castration in early life upon the development of the secondary sexual characters may readily be explained with reference to the individual differences that may be observed in the functional activity of the testicles in different males before the power of reproduction has been acquired. Just as in boys the capacity for reproduction, and in girls the function of menstruation, does not appear at a fixed and definite age, so also in the case of the other processes that come into being under the influence of the activity of the reproductive glands, we have to reckon with such individual differences. For this reason, in persons who have been castrated at the same age, the subsequent course of development may vary to some degree, notwithstanding the apparent identity of the determining factor in each case. In some, the pelvis, the beard, the voice, and the mental qualities, develop in normal fashion; in others, there is interference with the development of one or all of these characters. In certain cases, the bodily structure is influenced by castration at an age when the mental development is no longer affected. This explains the fact that many oriental eunuchs, in whom castration is commonly effected shortly before the seventh or eighth year of life, while they exhibit the bodily configuration characteristic of the eunuch, are nevertheless capable of experiencing heterosexual feelings, and even passionate love.

In Western countries we rarely have an opportunity of studying the full consequences of castration, for with us the operation is hardly ever performed so early in life as it is in the East; and the reports that are available concerning oriental and other foreign eunuchs are to a large extent untrustworthy. None the less, from such reports, and from accounts that have come down to us from earlier days in the West (more especially in the case of the boys who were formerly castrated in Italy for the preservation of the soprano voice), we obtain evidence amply sufficient to justify the statements made above. Even more convincing are observations made on the lower animals. For example, in horses which have been castrated at a very early age the sexual impulse remains undeveloped; but we have to contrast with this the fact that a certain number of geldings possess a well-marked sexual impulse, because in these animals, though they were gelded while still immature, the operation was performed too late. All these observations combine to justify the inference that long before spermatozoa capable of effecting fertilisation are formed in the testicles, changes occur in these glands which are of great importance in relation to the sexual life, both in the human species and in the lower animals.
