The Kama Sutra of Vatsyayana Translated From the Sanscrit...

The wives of other people may be resorted to on the occasions already described in Part I., Chapter 5, of this work, but the possibility of their acquisition, their fitness for cohabitation, the danger to oneself in uniting with them, and the future effect of these unions, should first of all be examined. A man may resort to the wife of another, for the purpose of saving his own life, when he perceives that his love for her proceeds from one degree of intensity to another. These degrees are ten in number, and are distinguished by the following marks:

Ancient authors say that a man should know the disposition, truthfulness, purity, and will of a young woman, as also the intensity, or weakness of her passions, from the form of her body, and from her characteristic marks and signs. But Vatsyayana is of opinion that the forms of bodies, and the characteristic marks or signs are but erring tests of character, and that women should be judged by their conduct, by the outward expression of their thoughts, and by the movements of their bodies.

Now as a general rule Gonikaputra says that a woman falls in love with every handsome man she sees, and so does every man at the sight of a beautiful woman, but frequently they do not take any further steps, owing to various considerations. In love the following circumstances are peculiar to the woman. She loves without regard to right or wrong,[58] and does not try to gain over a man simply for the attainment of some particular purpose. Moreover, when a man first makes up to her she naturally shrinks from him, even though she may be willing to unite herself with him. But when the attempts to gain her are repeated and renewed, she at last consents. But with a man, even though he may have begun to love, he conquers his feelings from a regard for morality and wisdom, and although his thoughts are often on the woman, he does not yield, even though an attempt be made to gain him over. He sometimes makes an attempt or effort to win the object of his affections, and having failed, he leaves her alone for the future. In the same way, when a woman is once gained, he often becomes indifferent about her. As for the saying that a man does not care for what is easily gained, and only desires a thing which cannot be obtained without difficulty, it is only a matter of talk.

Whichever of the above causes a man may detect, he should endeavour to remove it from the very beginning. Thus, the bashfulness that may arise from his greatness or his ability, he should remove by showing his great love and affection for her. The difficulty of the want of opportunity, or if his inaccessibility, he should remove by showing her some easy way of access. The excessive respect entertained by the woman for him should be removed by making himself very familiar. The difficulties that arise from his being thought a low character he should remove by showing his valour and his wisdom; those that come from neglect by extra attention; and those that arise from fear by giving her proper encouragement.
