The Kama Sutra

(1). When the woman holds the lingam in her yoni, draws it in, presses it, and keeps it thus in her for a long time, it is called the "pair of tongs."

(2). When, while engaged in congress, she turns round like a wheel, it is called the "top." This is learnt by practice only.

(3). When, on such an occasion, the man lifts up the middle part of his body, and the woman turns round her middle part, it is called the "swing."

When the woman is tired, she should place her forehead on that of her lover, and should thus take rest without disturbing the union of the organs, and when the woman has rested herself the man should turn round and begin the congress again.

There are also some verses on the subject as follows: "Though a woman is reserved, and keeps her feelings concealed, yet when she gets on the top of a man, she then shows all her love and desire. A man should gather from the actions of the woman of what disposition she is, and in what way she likes to be enjoyed. A woman during her monthly courses, a woman who has been lately confined, and a fat woman should not be made to act the part of a man."
