"About these things there cannot be either enumeration or any definite rule. Congress having once commenced, passion alone gives birth to all the acts of the parties." Such passionate actions and amorous gesticulations or movements, which arise on the spur of the moment, and during sexual intercourse, cannot be defined, and are as irregular as dreams. A horse having once attained the fifth degree of motion goes on with blind speed, regardless of pits, ditches, and posts in his way; and in the same manner a loving pair become blind with passion in the heat of congress, and go on with great impetuosity, paying not the least regard to excess. For this reason one who is well acquainted with the science of love, and knowing his own strength, as also the tenderness, impetuosity, and strength of the young woman, should act accordingly. The various modes of enjoyment are not for all times or for all persons, but they should only be used at the proper time, and in the proper countries and places. FOOTNOTE: [Footnote 38: Men who are well acquainted with the art of love are well aware how often one woman differs from another in her sighs and sounds during the time of congress. Some women like to be talked to in the most loving way, others in the most abusive way, and so on. Some women enjoy themselves with closed eyes in silence, others make a great noise over it, and some almost faint away. The great art is to ascertain what gives them the greatest pleasure, and what specialities they like best.] CHAPTER VIII. ABOUT WOMEN ACTING THE PART OF A MAN; AND OF THE WORK OF A MAN. When a woman sees that her lover is fatigued by constant congress, without having his desire satisfied, she should, with his permission, lay him down upon his back, and give him assistance by acting his part. She may also do this to satisfy the curiosity of her lover, or her own desire of novelty. There are two ways of doing this, the first is when during congress she turns round, and gets on the top of her lover, in such a manner as to continue the congress, without obstructing the pleasure of it; and the other is when she acts the man's part from the beginning. At such a time, with flowers in her hair hanging loose, and her smiles broken by hard breathings, she should press upon her lover's bosom with her own breasts, and lowering her head frequently, should do in return the same actions which he used to do before, returning his blows and chaffing him, should say, "I was laid down by you, and fatigued with hard congress, I shall now therefore lay you down in return." She should then again manifest her own bashfulness, her fatigue, and her desire of stopping the congress. In this way she should do the work of a man, which we shall presently relate. Whatever is done by a man for giving pleasure to a woman is called the work of a man, and is as follows:--
