[Japanese variant; elements vary by font and positioning] An「orifice or mouth」with「rod」and「pulled out of normal shape」with「emissions」as a mouth being distorted, being pulled or pushed into an abnormal shape. Alternative Chinese version of this glyph ought to provide clues as to overall usage with elements「orifice of no-longer-integrated foot in two hands」to achieve the same meanings as the Japanese version, noting that the Japanese did not generally dis-integrate feet as they did in dynastic China. Meaning DOING SOMETHING FOR SOMEONE ELSE, also to GIVE, DOING SOMETHING FOR ANOTHER that they cannot do alone.「No-longer-integrated foot orifice with rod emissions」describes another activity a person cannot do by himself (see 吳 as the Chinese variant): feet with a compartment used 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 or another of a 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.
　「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 bound feet」(after removing the binding cloths, of course)

　So, what is it that a dog can do but a man cannot do for himself, but would like to do, that would cause a「mouth to become distorted in high tension for a long time causing gasps with rod emissions」? The ability to perform autofellatio is present in only two or three males in a thousand (data for females unavailable, since perhaps they simply do not attempt a similar act as often as do males, or, may more easily locate a willing accomplice), indicating that natural selection has reduced this trait within the human population considerably, most probably because those males able to perform such a feat may have spent long periods doing so, leaving themselves open to predators attacking while the subject was wholly self-absorbed and defenseless. Hence, this allele has almost entirely been eliminated from the human gene pool.
