CHAPTER XV
A Description of the Use and Action of the several Generative Parts in Women.
The external parts, commonly called the pudenda, are designed to cover the great orifice and to receive the man's penis or yard in the act of sexual intercourse, and to give passage to the child and to the urine. The use of the wings and knobs, like myrtle berries, is for the security of the internal parts, closing the orifice and neck of the bladder and by their swelling up, to cause titillation and pleasure in those parts, and also to obstruct the involuntary passage of the urine.
The action of the clitoris in women is similar to that of the penis in men, viz., erection; and its lower end is the glans of the penis, and has the same name. And as the glans of man are the seat of the greatest pleasure in copulation, so is this in the woman.
The action and use of the neck on the womb is the same as that of the penis, viz., erection, brought about in different ways: first, in copulation it becomes erect and made straight for the passage of the penis into the womb;
secondly, whilst the passage is filled with the vital blood, it becomes narrower for embracing the penis; and the uses of this erection are twofold:—first, because if the neck of the womb were not erected, the man's yard could find no proper passage to the womb, and, secondly, it hinders any damage or injury that might ensue through the violent striking of the penis during the act of copulation.
