Plutarch Quaestiones Convivales 3.4.3

[3] And Florus replied: Methinks, sir, from the same topics I could draw conclusions against your assertion. For, first, they endure cold better, because one similar quality doth not so readily act upon another; and then again, their seed is not active in generation, but passive matter and nourishment to that which the male injects. But more, women grow effete sooner than men; that they burn better than the males proceeds from their fat, which is the coldest part of the body; and young men, or such as use exercise, have but little fat. Their monthly purgations do not prove the abundance, but the corruption and badness, of their blood; for being the superfluous and undigested part, and having no convenient vessel in the body, it flows out, and appears languid and feculent, by reason of the weakness of its heat. And the shivering that seizes them at the time of their purgations sufficiently proves that which flows from them is cold and undigested. And who will believe their smoothness to be an effect of heat rather than cold, when every body knows that the hottest parts of a man’s body are the most hairy? For all such excrements are thrust out by the heat, which opens and makes passages through the skin; but smoothness is a consequent of that closeness of the superficies which proceeds from condensing cold. And that the flesh of women is closer than that of men, you may be informed by those that lie with women that have anointed themselves with oil or other perfumes; for though they do not touch the women, yet they find themselves perfumed, their bodies by reason of their heat and rarety drawing the odor to them.
