Their entring on this work is call’d Copulation, which is the joining of the Male to the Female: And both of them are equally transported with a furious and restless Passion, occasion’d by a mix’d motion of pleasure and pain in the Genitals, which strongly excites a desire for each other.

As this Enjoyment is natural, there needs no Instruction; Instinct in all Animals directs the way of acting, that is most convenient for propagating their Species: And a Man, though brought up in never so great Ignorance, at his Age of Maturity naturally enclines to it, and needs no other Guide but the dictates of Nature to find out the center of Enjoyment.

But if Nature had not planted in the Genitals a sense of extraordinary pleasure in the amorous Engagement, Man would seldom give himself the trouble of Copulation: The cause of this pleasure some impute to the mixing of Spirits with the Seed, which give a pleasing tickling; and that this is encreas’d by the fineness and bending of the Nervous Fibres of the parts: Others are of opinion, that the Salt in the Seed, and the Spirits accompanying, prick the parts through which they pass and occasion such an agreeable Titillation: And some give this reason for the pleasure, that as in Eating we have an Enjoyment, which no part but the Tongue and Palate partake of; so in Copulation a peculiar pleasure arises, of which the Generation Organs are only sensible; and that Animals are mov’d to the Act of Generation, as they are to Eating.

The tickling Pleasure which affects Women, proceeds from the Emotion, that is excited when the Seed disengages it self from the Testicle, and passes through the Cavities of the ejaculatory Vessels, in order to be darted into the Womb. When a Woman is not with Child, the Seed is thrown into the Womb by the shortest Vessel, and when she is pregnant, the Seed is thrown into the Neck of the Womb by the longest Branch: And for this reason, big-belly’d Women are more passionately fond of Embraces than others; for the Seed spending more time in its intricate Passage, raises a more transporting and lasting Titillation.

In respect to the Parts of a Man employ’d in the work of Generation, the Yard when lank cannot go about it; and it may be so stiff, as not to be proper: And sometimes the erection of the Yard is so strong, that it is always bent: A large Yard does not stand so readily, as a small one; and when it does it cannot subsist so long, by reason it requires more Blood to fill it; and when full, it is heavier, and consequently apt to fall in a very little time: And the business of Generation suffers no alteration from the shortness or length of the Yard within the Neck of the Womb; for the office of the two round Ligaments, is to enforce the bottom of the Womb to approach the head of the Yard, in order to receive the Seed in time of Ejaculation: But ’tis as difficult a matter to perswade some Lascivious Females, that a Yard of small Dimensions is equally useful and pleasurable to one of a considerable Longitude and Circumference, as it is to perswade a Club of Ravenous Stomachs, that a thin shrivell’d Shoulder of Mutton is of equal Goodness with a Haunch of well-fed Venison.

The parts of Women frequently differ in their Extent and Furniture; a great many Husbands are such Fools, as to covet difficulty in their first Approaches; and to measure the Virtue of their Wives, by the labour of their consummating Attack; not considering Nature has so order’d, that the Privy Parts are in the same Condition with the Mouth and the Eyes; some are little, and others are large; so that those who have naturally the larger size, may be unjustly charg’d with Lewdness; and on the other hand, those, who by the natural disposition of the Parts are straighter, may after Copulation be reputed Virgins. A Little Woman may have a large Mouth, &c. and a large Woman a little one, whereby the lesser Person may have the more capacious Privities: And the same rule may be observ’d in Men, in respect to the Nose, which seems to have equal Authority in determining the Dimensions nature has provided in the Male, as the Mouth or Eyes in the Female.

Nature does not always observe an exact rule of Symmetry, the visible Limbs and Parts are oftentimes disproportion’d; we frequently see a large personable Man, supported with slender Legs, and a Dwarf equip’d with large nervous Calves; and the same want of proportion is certainly to be found in the Privities.

I have known a wanton Female marry a Person of an extraordinary Stature, in expectation of a large Pleasure, with Sorrow confess she was greatly mistaken. And as a strong Soil does not constantly afford the most plentiful Crop of productive Grain; so the Privy Parts of a robust Person, are not always stock’d with the greatest quantity of surrounding Ornaments.

But to return to the Privy Parts of Women; in some extraordinary cases, the Lips of the Matrix, may be so closely join’d, that a Yard of the smallest Size, cannot possibly enter (when they are to be artfully separated by a Surgeon:) And in other Females the Passage is so wide, that the largest Member will make its way without the least difficulty: And I at this time know a Gentleman very well provided in the parts of Generation (beyond what is common) that has had three Wives, all of them of unspotted Reputations, and the oldest not above Nineteen; who affirms that the Nights of consummation with each of his Spouses; he was in quite to the Testicles in his first penetrating attempt.

The same Gentleman has declar’d, that in his Youth, when his Curiosity led him to the utmost variety; he has sometimes met with a Lady of Pleasure, whose Parts must be suppos’d to be extended to the utmost latitude of Nature, and to which upon Examination, no binding Preparations had been applied; that he could not possibly enter in the most encountering Embrace, which sufficiently shews the incertainty of Nature, and the difficulty attending the proof of Virginity. And this Gentleman is of the same Opinion with many others, that a narrow entrance to the Privy Parts of a Female, very much impedes a mutual Enjoyment.
