When we glance over the history of flagellation and realize that, though whipping as a punishment has been very widespread and common, there have been periods and lands showing no clear knowledge of any sexual association of whipping, it becomes clear that whipping is not necessarily an algolagnic manifestation. It seems evident that there must be special circumstances, and perhaps a congenital predisposition, to bring out definitely the relationship of flagellation to the sexual impulse. Thus, Löwenfeld considers that only about 1 per cent, of people can be sexually excited by flagellation of the buttocks,[[112]] and Näcke also is decidedly of opinion that there can be no sexual pleasure in flagellation without predisposition, which is rare.[[113]] On these grounds many are of opinion that physical chastisement, provided it is moderate, seldom applied, and only to children who are quite healthy and vigorous, need not be absolutely prohibited.[[114]] But, however rare and abnormal a sexual response to actual flagellation may be in adults, we shall see that the general sexual association of whipping in the minds of children, and frequently of their elders, is by; no means rare and scarcely abnormal.

What is the cause of the connection between sexual emotion and whipping? A very simple physical cause has been believed by some to account fully for the phenomena. It is known that strong stimulation of the gluteal region may, especially under predisposing conditions, produce or heighten sexual excitement, by virtue of the fact that both regions are supplied by branches of the same nerve.

There is another reason why whipping should exert a sexual influence. As Féré especially has pointed out, in moderate amount it has a tonic effect, and as such has a general beneficial result in stimulating the whole body. This fact was, indeed, recognized by the classic physicians, and Galen regarded flagellation as a tonic.[[115]] Thus, not only must it be said that whipping, when applied to the gluteal region, has a direct influence in stimulating the sexual organs, but its general tonic influence must naturally extend to the sexual system.

It is possible that we must take into account here a biological factor, such as we have found involved in other forms of sadism and masochism. In this connection a lady writes to me: "With regard to the theory which connects the desire for whipping with the way in which animals make love, where blows or pressure on the hindquarters are almost a necessary preliminary to pleasure, have you ever noticed the way in which stags behave? Their does seem as timid as the males are excitable, and the blows inflicted on them by the horns of their mates to reduce them to submission must be, I should think, an exact equivalent to being beaten with a stick."

It is remarkable that in some cases the whip would even appear to have a psychic influence in producing sexual excitement in animals accustomed to its application as a stimulant to action. Thus, Professor Cornevin, of Lyons, describes the case of a Hungarian stallion, otherwise quite potent, in whom erection could only be produced in the presence of a mare in heat when a whip was cracked near him, and occasionally applied gently to his legs. (Cornevin, Archives d'Anthropologie Criminelle, January, 1896.)

Here, undoubtedly, we have a definite anatomical and physiological relationship which often serves as a starting-point for the turning of the sexual feelings in this direction, and will sometimes support the perversion when it has otherwise arisen. But this relationship, even if we regard it as a fairly frequent channel by which sexual emotion is aroused, will not suffice to account for most, or even many, of the cases in which whipping exerts a sexual fascination. In many, if not most, cases it is found that the idea of whipping asserts its sexual significance quite apart from any personal experience, even in persons who have never been whipped;[[116]] not seldom also in persons who have been whipped and who feel nothing but repugnance for the actual performance, attractive as it may be in imagination.

It is evident that we have to seek the explanation of this phenomenon largely in psychic causes. Whipping, whether inflicted or suffered, tends to arouse, vaguely but massively, the very fundamental and primitive emotions of anger and fear, which, as we have seen, have always been associated with courtship, and it tends to arouse them at an age when the sexual emotions have not become clearly defined, and under circumstances which are likely to introduce sexual associations. From their earliest years children have been trained to fear whipping, even when not actually submitted to it, and an unjust punishment of this kind, whether inflicted on themselves or others, frequently arouses intense anger, nervous excitement, or terror in the sensitive minds of children.[[117]] Moreover, as has been pointed out to me by a lady who herself in early life was affected by the sexual associations of whipping, a child only sees the naked body of elder children when uncovered for whipping, and its sexual charm may in part be due to this cause. We further have to remark that the spectacle of suffering itself is, to some extent and under some circumstances, a stimulant of sexual emotion. It is evident that a number of factors contribute to surround whipping at a very early age with powerful emotional associations, and that these associations are of such a character that in predisposed subjects they are very easily led into a sexual channel.[[118]] Various lines of evidence support this conclusion. Thus, from several reliable quarters I learn that the sight of a boy being caned at school may produce sexual excitement in the boys who look on. The association of sexual emotion with whipping is, again, very liable to show itself in schoolmasters, and many cases have been recorded in which the flogging of boys, under the stress of this impulse, has been carried to extreme lengths. An early and eminent example is furnished by Udall, the humanist, at one time headmaster of Eton, who was noted for his habit of inflicting frequent corporal punishment for little or no cause, and who confessed to sexual practices with the boys under his care.[[119]]

Sanitchenko has called attention to the case of a Russian functionary, a school inspector, who every day had some fifty pupils flogged in his presence, as evidence of a morbid pleasure in such scenes. Even when no sexual element can be distinctly traced, scenes of whipping sometimes exert a singular fascination on some persons of sensitive emotional temperament. A friend, a clergyman, who has read many novels tells me that he has been struck by the frequency with which novelists describe such scenes with much luxury of detail; his list includes novels by well-known religious writers of both sexes. In some of these cases there is reason to believe that the writers felt this sexual association of whipping.

It is natural that an interest in whipping should be developed very early in childhood, and, indeed, it enters very frequently into the games of young children, and constitutes a much relished element of such games, more especially among girls. I know of many cases in which young girls between 6 and 12 years of age took great pleasure in games in which the chief point consisted in unfastening each other's drawers and smacking each other, and some of these girls, when they grew older, realized that there was an element of sexual enjoyment in their games. It has indeed, it seems, always been a child's game, and even an amusement of older persons, to play at smacking each other's nates. In The Presbyter's Lash in 1661 a young woman is represented as stating that she had done this as a child, and in ancient France it was a privileged custom on Innocents' Day (December 28th) to smack all the young people found lying late in bed; it was a custom which, as Clement Marot bears witness, was attractive to lovers.

If we turn to the histories I have brought together in Appendix B we find various references to whipping more or less clearly connected with the rudimentary sexual feelings of childhood.
