The following kinds of men are not fit to be resorted to by courtesans, viz.: One who is consumptive; one who is sickly; one whose mouth contains worms; one whose breath smells like human excrement; one whose wife is dear to him; one who speaks harshly; one who is always suspicious; one who is avaricious; one who is pitiless; one who is a thief; one who is self-conceited; one who has a liking for sorcery; one who does not care for respect or disrespect; one who can be gained over even by his enemies by means of money; and lastly, one who is extremely bashful. Ancient authors are of opinion that the causes of a courtesan resorting to men are love, fear, money, pleasure, returning some act of enmity, curiosity, sorrow, constant intercourse, Dharma, celebrity, compassion, the desire of having a friend, shame, the likeness of the man to some beloved person, the search after good fortune, the getting rid of the love of somebody else, the being of the same class as the man with respect to sexual union, living in the same place, constancy, and poverty. But Vatsyayana decides that desire of wealth, freedom from misfortune, and love, are the only causes that affect the union of courtesans with men. Now a courtesan should not sacrifice money to her love, because money is the chief thing to be attended to. But in cases of fear, etc., she should pay regard to strength and other qualities. Moreover, even though she be invited by any man to join him, she should not at once consent to an union, because men are apt to despise things which are easily acquired. On such occasions she should first send the shampooers, and the singers, and the jesters, who may be in her service, or, in their absence the Pithamardas, or confidants, and others, to find out the state of his feelings, and the condition of his mind. By means of these persons she should ascertain whether the man is pure or impure, affected, or the reverse, capable of attachment, or indifferent, liberal or niggardly; and if she finds him to her liking, she should then employ the Vita and others to attach his mind to her.
