much, as some of the female sperm may penetrate into his urethra, and grave malady may ensue that the man's sperm cannot pass out, and returns into therefrom. It may also happen that the man's sperm cannot pass out, and returns into the urethra.
If the man prefers that the woman should lie on her back, he places himself, with his legs folded under him, between her legs, which she parts only moderately. Thus, his buttocks are between the women's legs, with his heels touching them. In doing that way he will, however, feel fatigue, owing to the position of his stomach resting upon the woman's and the inconvenience resulting therefrom; and, besides, he will not be able to get his whole member in the vulva.
It will be about the same when both lie on their sides as mentioned above in the case of pregnant women, where the manner is described.
When both man and woman are fat, and are wanting to unite themselves in coition, they cannot contrive to do it without trouble, particularly when both have prominent stomachs. In these circumstances the best way to go about it is for the woman to be on her knees with her hands on the ground, so that her posterior is elevated; then the man separates her legs, leaving the points of the feet close together and the heels parted asunder; he then attacks her from behind, kneeling and holding up his stomach with his hand, and so introduces his member. Resting his stomach upon her buttocks he holds during the act the thighs or the waist of the woman with his, hands. If the posterior of the woman is too low for his stomach to rest upon, he must place a cushion under her knees, to remedy this.
