Indian logician, author of Kama Sutra
Vātsyāyana, also spelled Vatsayana, is an ancient Indian philosopher, known for writing the Kama Sutra, the most ancient book in the world on human sexuality. He lived in India during the second or third century CE, probably in Pataliputra (modern day Patna). He is not to be confused with Pakṣilasvāmin Vātsyāyana, the author of Nyāya Sutra Bhāshya, the first preserved commentary on Gotama's Nyāya Sutras. His name is sometimes erroneously confused with Mallanaga, the prophet of the Asuras, to whom the origin of erotic science is attributed.

It is easy to remember the three-fold formula of success in a sexual union: size, time and temperament. Vatsayana has given his candid opinion about licking the vulva and sucking the penis. Licking the vulva is not forbidden by the acharyas or texts, if it is custom of the country...There are many countries where mouth congress is enjoyed.
...showing the difference between men and women in their enjoyment of sex, Vatsyayan offers a good deal of information about human sexuality in general, Vatsyana offers a taxonomical picture of men and women as far as their genitals are concerned....Vatsyana talks of the hare man, the bull man and the stallion...similarly according to the width and depth of the vulva, he speaks of gazelle woman, the mare woman and the elephant woman.
In order to convince the narrator that woman enjoys sex more intensely than man Vatsayana offers a few mythological examples. For example, Lord Shiva "on insulting a procession of barren women was cursed by the women with a change of sex. Later transformed back into his original state but now familiar with both men and women he is said to have dictated Dattaka’s text to that great teacher of erotics.
No details of Vatsayana is known except the fact that he bore the surname Mallanaga... He was a law giver like Manu or Kauitilya and was anxious to reconcile Dharma, Artha and Kama the three recognized ends of life by emphasizing their equal importance and harmonious blending, and hence it was not possible for him to reduce his work to gross sexual level as did his successors or imitators in the subsequent erotic writing.
It is indeed strange that Indian critics should react to this novel so puritanically, forgetting the fact that a masterpiece of erotics i.e. Kama Sutra was produced by Vatsayana in the ancient days in India. Like all semi or fully pornographic novels, The Company of Women is widely sold, secret and publicly condemned.
The work being written in parts by different authors was almost unobtainable and, as the parts which were expounded by Dattaka and the others treated only of the particular branches of the subject to which each part related, and moreover as the original work of Babhravya was difficult to be mastered on account of its length, Vatsyayana, therefore, composed his work in a small volume as an abstract of the whole of the works of the above various authors.
The 'Aphorisms on Love' by Vatsyayana, contains about one thousand two hundred and fifty slokas or verses, and are divided into parts, parts into chapters, and chapters into paragraphs. The whole consists of seven parts, thirty-six chapters, and sixty-four paragraphs. Hardly anything is known about the author.
When a woman reproaches a man, but at the same time acts affectionately towards him, she should be made love to in every way. A woman, who meets a man in lonely places, and puts up with the touch of his foot, but pretends, on account of indecision of her mind, not to be aware of it, should be conquered by patience and by continued efforts.
