Fellatio and cunnilinctus, while they are not strictly methods of coitus, in so far as they do not involve the penetration of the penis into the vagina, are very widespread as preliminaries, or as vicarious forms of coitus, alike among civilized and uncivilized peoples. Thus, in India, I am told that fellatio is almost universal in households, and regarded as a natural duty towards the paterfamilias. As regards cunnilinctus Max Dessoir has stated (Allgemeine Zeitschrift für Psychiatrie, 1894, Heft 5) that the superior Berlin prostitutes say that about a quarter of their clients desire to exercise this, and that in France and Italy the proportion is higher; the number of women who find cunnilinctus agreeable is without doubt much greater. Intercourse per anum must also be regarded as a vicarious form of coitus. It appears to be not uncommon, especially among the lower social classes, and while most often due to the wish to avoid conception, it is also sometimes practiced as a sexual aberration, at the wish either of the man or the woman, the anus being to some extent an erogenous zone.

The ethnic variations in method of coitus were briefly discussed in volume v of these Studies, "The Mechanism of Detumescence," Section II. In all civilized countries, from the earliest times, writers on the erotic art have formally and systematically set forth the different positions for coitus. The earliest writing of this kind now extant seems to be an Egyptian papyrus preserved at Turin of the date B.C. 1300; in this, fourteen different positions are represented. The Indians, according to Iwan Bloch, recognize altogether forty-eight different positions; the Ananga Ranga describes thirty-two main forms. The Mohammedan Perfumed Garden describes forty forms, as well as six different kinds of movement during coitus. The Eastern books of this kind are, on the whole, superior to those that have been produced by the Western world, not only by their greater thoroughness, but by the higher spirit by which they have often been inspired.

The ancient Greek erotic writings, now all lost, in which the modes of coitus were described, were nearly all attributed to women. According to a legend recorded by Suidas, the earliest writer of this kind was Astyanassa, the maid of Helen of Troy. Elephantis, the poetess, is supposed to have enumerated nine different postures. Numerous women of later date wrote on these subjects, and one book is attributed to Polycrates, the sophist.

Aretino—who wrote after the influence of Christianity had degraded erotic matters perilously near to that region of pornography from which they are only to-day beginning to be rescued—in his Sonnetti Lussuriosi described twenty-six different methods of coitus, each one accompanied by an illustrative design by Giulio Romano, the chief among Raphael's pupils. Veniero, in his Puttana Errante, described thirty-two positions. More recently Forberg, the chief modern authority, has enumerated ninety positions, but, it is said, only forty-eight can, even on the most liberal estimate, be regarded as coming within the range of normal variation.

The disgrace which has overtaken the sexual act, and rendered it a deed of darkness, is doubtless largely responsible for the fact that the chief time for its consummation among modern civilized peoples is the darkness of the early night in stuffy bedrooms when the fatigue of the day's labors is struggling with the artificial stimulation produced by heavy meals and alcoholic drinks. This habit is partly responsible for the indifference or even disgust with which women sometimes view coitus.

Many more primitive peoples are wiser. The New Guinea Papuans of Astrolabe Bay, according to Vahness (Zeitschrift für Ethnologie, 1900, Heft 5, p. 414), though it must be remembered that the association of the sexual act with darkness is much older than Christianity, and connected with early religious notions (cf. Hesiod, Works and Days, Bk. II), always have sexual intercourse in the open air. The hard-working women of the Gebvuka and Buru Islands, again, are too tired for coitus at night; it is carried out in the day time under the trees, and the Serang Islanders also have coitus in the woods (Ploss and Bartels, Das Weib, Bk. i, Ch. XVII).

It is obviously impracticable to follow these examples in modern cities, even if avocation and climate permitted. It is also agreed that sexual intercourse should be followed by repose. There seems to be little doubt, however, that the early morning and the daylight are a more favorable time than the early night. Conception should take place in the light, said Michelet (L'Amour, p. 153); sexual intercourse in the darkness of night is an act committed with a mere female animal; in the day-time it is union with a loving and beloved individual person.

This has been widely recognized. The Greeks, as we gather from Aristophanes in the Archarnians, regarded sunrise as the appropriate time for coitus. The South Slavs also say that dawn is the time for coitus. Many modern authorities have urged the advantages of early morning coitus. Morning, said Roubaud (Traité de l'Impuissance, pp. 151-3) is the time for coitus, and even if desire is greater in the evening, pleasure is greater in the morning. Osiander also advised early morning coitus, and Venette, in an earlier century, discussing "at what hour a man should amorously embrace his wife" (La Génération de l'Homme, Part II, Ch. V), while thinking it is best to follow inclination, remarks that "a beautiful woman looks better by sunlight than by candlelight." A few authorities, like Burdach, have been content to accept the custom of night coitus, and Busch (Das Geschlechtsleben des Weibes, vol. i, p. 214) was inclined to think the darkness of night the most "natural" time, while Fürbringer (Senator and Kaminer, Health and Disease in Relation to Marriage, vol. i, p. 217) thinks that early morning is "occasionally" the best time.

To some, on the other hand, the exercise of sexual intercourse in the sunlight and the open air seems so important that they are inclined to elevate it to the rank of a religious exercise. I quote from a communication on this point received from Australia: "This shameful thing that must not be spoken of or done (except in the dark) will some day, I believe, become the one religious ceremony of the human race, in the spring. (Oh, what springs!) People will have become very sane, well-bred, aristocratic (all of them aristocrats), and on the whole opposed to rites and superstitions, for they will have a perfect knowledge of the past. The coition of lovers in the springtime will be the one religious ceremony they will allow themselves. I have a vision sometimes of the holy scene, but I am afraid it is too beautiful to describe. 'The intercourse of the sexes, I have dreamed, is ineffably beautiful, too fair to be remembered,' wrote the chaste Thoreau. Verily human beauty, joy, and love will reach their divinest height during those inaugural days of springtide coupling. When the world is one Paradise, the consummation of the lovers, the youngest and most beautiful, will take place in certain sacred valleys in sight of thousands assembled to witness it. For days it will take place in these valleys where the sun will rise on a dream of passionate voices, of clinging human forms, of flowers and waters, and the purple and gold of the sunrise are reflected on hills illumined with pansies. [I know not if the writer recalled George Chapman's "Enamelled pansies used at nuptials still">[, and repeated on golden human flesh and human hair. In these sacred valleys the subtle perfume of the pansies will mingle with the divine fragrance of healthy naked young women and men in the spring coupling. You and I shall not see that, but we may help to make it possible." This rhapsody (an unconscious repetition of Saint-Lambert's at Mlle. Quinault's table in the eighteenth century) serves to illustrate the revolt which tends to take place against the unnatural and artificial degradation of the sexual act.

In some parts of the world it has seemed perfectly natural and reasonable that so great and significant an act as that of coitus should be consecrated to the divinity, and hence arose the custom of prayer before sexual intercourse. Thus Zoroaster ordained that a married couple should pray before coitus, and after the act they should say together: "O, Sapondomad, I trust this seed to thee, preserve it for me, for it is a man." In the Gorong Archipelago it is customary also for husband and wife to pray together before the sexual act (Ploss and Bartels, Das Weib, Bd. i, Ch. XVII). The civilized man, however, has come to regard his stomach as the most important of his organs, and he utters his conventional grace, not before love, but only before food. Even the degraded ritual vestiges of the religious recognition of coitus are difficult to find in Europe. We may perhaps detect it among the Spaniards, with their tenacious instinct for ritual, in the solemn etiquette with which, in the seventeenth century, it was customary, according to Madame d'Aulnoy, for the King to enter the bedchamber of the Queen: "He has on his slippers, his black mantle over his shoulder, his shield on one arm, a bottle hanging by a cord over the other arm (this bottle is not to drink from, but for a quite opposite purpose, which you will guess). With all this the King must also have his great sword in one hand and a dark lantern in the other. In this way he must enter, alone, the Queen's chamber" (Madame d'Aulnoy, Relation du Voyage d'Espagne, 1692, vol. iii, p. 221).
