Modern elements appear as「female role, rod with tonguing mouth」with「prick within an orifice, measurement」or「the place where birthing occurs」or「female role, inside soil walls」as in an ESTIMATED MEASURE of AMOUNT, VISCOSITY, DOSE, VOLUME, WEIGHT, MAGNITUDE, TEMPERATURE DEGREES or what have you that is related to her body, and not likely referring literally to the clay content of the muck in the backyard rice paddy. Frankly, the average adult male human paired with the average adult female human will most likely not encounter any problem related to CAPACITY or VOLUME of what a particular orifice can hold. But on the contrary, an adult male paired with a child of either sex will most likely encounter a gland-to-orifice ratio that exceeds rated capacity, so this became a problem to be considered by the dynastic Chinese often enough that this glyph now represents HOW MUCH CAN THAT HOLD? WILL IT ALL FIT INSIDE? (「rod with tonguing mouth and soil walls」)
ESTIMATES of CAPACITY, VOLUME, VISCOSITY, HEATED TEMPERATURE and so on also relate directly to an adult female caregiver for a male child in dynastic China, be she his birth mother or a nanny:
「Historical accounts from the 18th century indicate that adult-child sex (particularly same-sex pairings) were an accepted practice in China, Japan, Africa, Turkey, Arabia, Egypt, and the Islamic areas of India (Trumbach, 1977). In 19th century London the going price for a virginal, 12-year-old girl, of good background, was reported to be 400 pounds (Bullough, 1964).」

In dynastic China:「A male child of any age, even before birth, could by parental arrangement take an adult woman as a wife. The purpose could be to consolidate family status and relationship, or simply to have someone to help taking care of the child. After marriage, the couple slept in one bed like all other husbands and wives. No one would pay attention to what type of sexual relationship they might have and when. In the normal course of events, they would begin with those sex plays they were capable of and wanted, until one day, when the child was old enough to desire and do it, they had coitus. After the boy grew still older, he usually took a second wife closer to his age, but he would continue to keep, love and respect the first wife. Some writers very vehemently question the capacity of children to give valid consent to sexual activity with adults. Despite their arguments, to the Chinese - who are particularly conscious of the importance and priority of social (and hence adult) values - the focus of discussions on the child consent issue in pedophilic activities is blatantly irrelevant and hypocritical.」

Perhaps even one's own mother will perform these measurements:「In Japan, it is not uncommon for mothers to sexually stimulate their children to soothe them so they will sleep. There have been stories in the press of mother-son incest arising from the strong nature of this relationship in Japan and the important maternal role of ensuring the son succeeds at school. According to Hideo Tokuoka, 'When Americans think of incest, they think of fathers and daughters. In Japan one thinks of mothers and sons' due to the extensive media coverage of mother-son incest there.」
