tasyāḥ prāg yantrayogāt kareṇa saṃbādhaṃ gaja eva kṣobhayet/ ā mṛdubhāvāt/ tato yantrayojanam//

The signs of the enjoyment and satisfaction of the woman are as follows: her body relaxes, she closes her eyes, she puts aside all bashfulness, and shows increased willingness to unite the two organs as closely together as possible. On the other hand, the signs of her want of enjoyment and of failing to be satisfied are as follows: she shakes her hands, she does not let the man get up, feels dejected, bites the man, kicks him, and continues to go on moving after the man has finished. In such cases the man should rub the yoni of the woman with his hand and fingers (as the elephant rubs anything with his trunk) before engaging in congress, until it is softened, and after that is done he should proceed to put his lingam into her.
