As depicted in erotic Chinese art: TO VIOLATE in some manner whilst engaging in any sort of 「motions with an orifice.」Rather than perpetuate the spread of disease resulting from motions with an orifice on a regular basis, the ancient Chinese shamans conceived of a possible solution to the problem, described as follows.「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course).

SOMEONE WHO MUST SIT MOST OF THE TIME due to having her feet no-longer-integrated in dynastic China, and whose busted feet were used as a scoop for temporarily holding fluids that have been ejaculated from a human dirk (read: 'dick' in the common parlance, as a tool used for stabbing flesh)...see ancient Chinese erotic art for many examples depicting this behavior, and as the reason that the "bound feet of women with the metatarsal bones pulverized were highly erotic in ancient China," a fact that today is too embarrassing to be openly admitted any longer. So, history must be rewritten, and these glyphs must have been created "for the sound" used in pronunciation...you believe that?
Dis-integrating the feet of little girls and selling them as sex slaves to use their feet as a masturbatory aid and to hinder flight is no longer socially acceptable (and quite rightly, too).
「Evolutionary biologists have traced the origins of masturbation to ancient primates that predate the first humans by tens of millions of years. The findings emerged from what scientists believe is the largest dataset ever compiled on the activity, and confirm that humans arose on a branch of the tree of life replete with self-pleasuring predecessors. 'What we can say is this behaviour was present around 40m (40,000,000) years ago, in the common ancestor of all monkeys and apes,' said Dr Matilda Brindle, the lead researcher on the study at University College London. 'It's not that some species woke up one day and started doing it. This is an ancient, evolved trait.' '…This is such a common behaviour across the animal kingdom, I find it absolutely baffling that nobody has researched it before,' said Brindle. 'For people who think masturbation is wrong, or unnatural in some way, this is perfectly natural behaviour. It's part of our healthy repertoire of sexual behaviours.'」

「Viewing women as commodities [see 品] was also made customary…, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」

「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter [such as, masturbation]. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

See also https://scholarworks.iu.edu/journals/index.php/iusburj/article/download/19830/25907/ for additional details: foot-binding, infanticide, concubinage, prostitution, and other Chinese practices affecting females were not outlawed until 1950. Moreover, the law and actual practice are never fully synchronized in any society.
Still a problem in 2021 (and today, too, whenever you read this):「The issue of 'child marriage,' when girls are forced to marry older men for money, has worsened during the coronavirus crisis. The UN Population Fund says more than 33,000 girls worldwide are forced into wedlock every day. The problem was already serious in Pakistan, but financial burdens caused by the pandemic are putting even more children at risk.」

In the sticky heat of a June day in Juba, South Sudan’s capital in 2024, a girl aged 14 years (still attending elementary school) was sold as a「bride」for a payment of 123 cattle, 120 million South Sudanese pounds (about $44,000 or £33,000) in cash, and a plot of land…she was dubbed「the most expensive bride in South Sudan」in TikTok videos that gained thousands of likes. What a world, what humans do…

「Until the Chinese communists took power in 1949, bigamy, concubinage and child marriage were commonplace. In 1950, Beijing enacted a new law that outlawed these practices. The law also enforced monogamy in an effort to make women more equal to men in Chinese society.」 [ https://www.theguardian.com/world/2021/jun/18/chinese-academic-suspended-for-advocating-polygamy 2021-06-19 ]
Marriage is a relatively recent institution in our species’ 300,000-plus-years of history, originating perhaps 5,000 years ago in Mesopotamia, and until quite recently, almost everywhere, served only to bind women to men as property assets, to ensure paternity, and protect the male's lineage among descendants. (And in some parts of the world, this is still the norm.) That puts marriage at ~1–2% of the age of the existence of Homo sapiens as a species (or, 0% in some parts of the world where this is still the norm).
