Auddalika says, “Females do not emit as males do. The males simply remove their desire, while the females, from their consciousness of desire, feel a certain kind of pleasure, which gives them satisfaction, but it is impossible for them to tell you what kind of pleasure they feel. The fact from which this becomes evident is, that males, when engaged in coition, cease of themselves after emission, and are satisfied, but it is not so with females.”
