「Rod head with concubine」「man with service provider」may cause portions to be TRANSFORMED involuntarily, a change that occurs in both his heads after being CHARMED, ENCHANTED, BEWITCHED by the possibilities of his snake being charmed, raising itself due to the skillful touch of a beautiful vixen as sex rears its ugly head, again.
　A change intended to IMPROVE…perhaps referring to the dynastic Chinese practice of dis-integrating the feet of a young girl in order to make her more sexually useful (but also sitting most of the time for the remainder of her life):
　「Viewing women as commodities [see 品] was also made customary from Song Dynasty (960 - 1279) forward, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」

　As depicted in erotic Chinese art, men in dynastic China masturbated by wrapping no-longer-integrated feet around an erect penis ostensibly to lower the risk of contracting a sexually transmissible disease or infection that often occurred when performing coitus within some sort of mucous membrane system of a female service provider, and, to gain hand-control over the pressure applied to the foot meat surrounding a weakened penis that functioned as a living cockring:「Women, their families, and [her owner] took great pride in tiny feet, with the ideal length, called the 'Golden Lotus,' being about 7 cm (2.75 inches) long. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Bound feet were once considered intensely erotic in Chinese culture. …Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」

　「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. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」
