QUOTE : In an essay almost entirely about sex, Montaigne cites the wisdom of Aristotle: “A man … should touch his wife prudently and soberly, lest if he caresses her too lasciviously the pleasure should transport her outside the bounds of reason.” The physicians warned, too, that excessive pleasure could make sperm curdle inside the woman’s body, rendering her unable to conceive. It was better for the husband to bestow ecstasy elsewhere, where it did not matter what damage it caused. “The kings of Persia,” relates Montaigne, “used to invite their wives to join them at their feasts; but when the wine began to heat them in good earnest and they had to give completely free rein to sensuality, they sent them back to their private rooms.” They then brought on a more suitable set of women.
