A BRIEF EXCERPT FROM WIND BY XINYUE ZHUREN
Presented here is a brief excerpt from "Wind", the first of the four Greek love stories that make up Yi-chun Xiang-zhi 宜春香質 (Pleasant Spring and Fragrant Character), an erotic Chinese novel written during the Chonghzen reign (1628-44) by a writer calling himself Zuixihu Xinyue Zhuren 醉西湖心月主人 (The Moon-Heart Master of the Drunken West Lake).
The translation is from Sex in China: Studies in Sexology in Chinese Culture by Fang Fu Ruan, who introduced it thus:
The Ching dynasty novel providing the most detailed and concrete descriptions of homosexual lovemaking would have to be Pleasant Spring and Fragrant Character (Yi-chun Xiang-zhi). This novel, written under the pseudonym Xin Yue Zhu Ren, was so rare it was not even included in standard bibliographies listing works with sexual themes (e.g., Sun Kai-ti, 1982; Liu Cun-ren, 1982). However, it was included on lists of books officially banned during the Dao Guang (1821-1850) and Tung Chih (1862-1874) periods. As a banned book, it was rarely circulated, and the edition referred to here is a handwritten copy stored in the Beijing Library.
The work contains four volumes, respectively titled Wind, Flower, Snow, and Moon. Each volume is an independent story with five chapters and contains numerous descriptions of homosexual behavior and acts. One of the simpler, more easily understood portions, quoted here, illustrates the wealth of detail contained in this novel.
The scene takes place in Chapter 1, Volume 1, between Li Zun-xian, an eighteen-year-old student, and Sun Yi-zhi, a thirteen-year-old student:
Li's penis had reached Sun's anus and was fully erect but could not enter. Despite several attempts in different ways, Li still could not succeed in entering Sun. Meanwhile Sun was screaming with pain and begged Li to stop. Li told Sun that he did not want to hurt him, but the really wonderful sensations would come later. Li also told Sun that it would help if Sun moved his buttocks. Sun replied that it hurt everywhere, so Li might as well come into him.
Li instructed Sun to hold his own buttocks and then bear down. He would enter Sun at that time. Meanwhile, Li lubricated his penis with his saliva, and with a strong push succeeded in entering Sun. Sun's inside was still quite tight and dry. Li used another strong push, inserting the whole length of his penis. Li then forcefully pushed up and down, in and out. Gradually, Sun's inside began to feel smooth and slippery. Li could now enter and withdraw easily. Sun began to feel as if liquid were flooding his inside, and had a strong sensual feeling. He began to move his buttocks up and down until he could hardly breathe and indulged himself in this pleasure.
Li knew then that Sun was enjoying himself, and pushed his penis with great force while Sun was resting, catching his breath. It was at this point that Sun reached his sexual climax. He moaned, "Dear brother!" and turned around and kissed Li on the mouth.

 Fang Fu Ruan, Sex in China: Studies in Sexology in Chinese Culture, New York, 1991, pp. 116-7. Ruan also says “the novel appears to have been written between 1796 and 1843, and can safely be said to belong to the first half of the nineteenth century, “ but this is contradicted by works of more recent scholarship, for example Mark Stevenson and Wu Cuncun in their Homoeroticism in Imperial China: A Sourcebook (Abingdon, Oxon.: Routledge, 2013), pp. 184-192, who also there give a translation of another excerpt from it.
