The Perfumed Garden
Chapter 13 - Concerning the Causes of Enjoyment in the Act of Generation
Know, O Vizir (to whom God be good!), that the causes which tend to develop the passion for coition are six in number:
the fire of an ardent love, the superabundance of sperm, the proximity of the loved person
whose possession is eagerly desired, the beauty of the face, exciting viands, and contact.
Know also, that the causes of the pleasure in cohabitation, and the conditions of enjoyment are numerous,
but that the principal and best ones are: the heat of the vulva; the narrowness, dryness,
and sweet exhalation of the same. If any one of these conditions is absent,
there is at the same time something wanting in the voluptuous enjoyment.
But if the vagina unites the required qualifications, the enjoyment is complete.
In fact, a moist vulva relaxes the nerves, a cold one robs the member of all its vigour,
and bad exhalations from the vagina detract greatly from the pleasure, as is also the case if the latter is very wide.
The acme of enjoyment, which is produced by the abundance and impetuous ejaculation of the sperm,
depends upon one circumstance, and this is, that the vulva is furnished with a suction-pump (orifice of the uterus),
which will clasp the virile member, and suck up the sperm with an irresistible force.
The member once seized by the orifice, the lover is powerless to retain the sperm,
for the orifice will not relax its hold until it has extracted every drop of the sperm,
and certainly if the crisis arrives before this gripping of the gland takes place,
the pleasure of the ejaculation will not be complete.
Know that there are eight things which give strength to and favour the ejaculation.
These are: bodily health, the absence of all care and worry, an unembarrassed mind, natural gaiety of spirit,
good nourishment, wealth, the variety of the faces of women, and the variety of their complexions.
If you wish to acquire strength for coitus, take fruit of the mastic tree (derou),
pound them and macerate them with oil and honey; then drink of the liquid first thing in the morning:
you will thus become vigorous for the coitus, and there will be abundance of sperm produced.
