[Elements vary by font: see 每] upper and outer elements are「person prostrate, rod with sliding head」above「loose no-longer-integrated foot, tense gasping for a long time.」…inner element is「hand, erection rod (毋)」in traditional Chinese fonts, covering as if holding the loosened foot, but「screwing」in Japanese usage. Taken together, suggests the need for orgasmic climax on a regular and FREQUENT interval for EACH, EVERY person. Glyph realistically recognizes that sort of activity also occurred FREQUENTLY, REPEATING AT A CONSTANT INTERVAL. Blame evolution, alien overlords, the gods, or whatever you believe, but the need for sex is built into all living things, else those species would not reproduce sufficiently and will become extinct…perhaps the various species not needing sex as much have already died out, which is why of virtually all the species remaining alive today, individuals need sex; of course, not sex necessarily with no-longer-integrated feet though—that was cultivated in China as a countermeasure for other perceived social ills.
　「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)

　Japanese variant changed the original Chinese into「prostrate, rod head sliding with mother.」…see 侮, 悔, 梅, 鋂 as references to actually having sex with one's own mother and not merely name-calling. However, note that「prostrate with do not, be not, must not」and「prostrate with female, mother」are used interchangeably only in Japanese variants. Whether these two glyphs have something to do with incest or not, in the old days most EVERY person was forced through their mother's vaginal canal at birth (or she died when her abdomen was sliced open).「Mother lying prostrate」as REPEATING AT A CONSTANT INTERVAL suggests birthing sessions with all of her offspring ONE BY ONE AND EACH SEQUENTIALLY, RESPECTIVELY, ON A REGULAR BASIS (at least one year apart, perhaps) the process of lying prostrate during the act that caused conception (vaginal coitus, in the old days), giving birth, nursing the infant at night…and then repeating the whole thing again and again, year after year.
　「To lie prostrate」combined with various other elements, such as「penetration」or「plugging orifice with erection」or「screwing inside female」also suggest the processes of conception and birth, respectively. Furthermore, try as one might, a male human can only be「prostrate and penetrating orifices with erection」ONE AT A TIME, ONE BY ONE, SEQUENTIALLY REPEATING AT A CONSTANT INTERVAL, and so on. Furthermore, only ONE AT A TIME can「lie prostrate whilst engaging rod within a set of breasts」since both are essential for sufficient friction and balancing lateral tension…mammary intercourse with a single breast is akin to one hand clapping: ineffectual at best, but entertaining to witness.
