Glyph may depict an eclectic range of meanings, so be sure to see all the Used-In glyphs for specific confirmation of intent.「Gain control of rod in orifice」or「gain control of tonguing mouth」as something that DOES NOT HAPPEN, since the former is so much desired and the latter is so much effective at subduing others.
　「Emerging shafts with tonguing mouth two-handed」depicts a male human attempting to AUTO-FELLATE, an event that MAY NEVER OCCUR but always entails a DOWNWARD MOTION by an IMBECILE. Due to visual perspective, as one's eyes approach an object, the object tends to appear larger relative to its surroundings, hence an IMBECILE in DOWNWARD MOTION with「tonguing mouth approaching emerging shaft」will likely see an increasingly「big」image of himself. Failure to achieve the desired end will always leave a gap to SEE-THROUGH between the two approaching but unreachable tips, especially as the eyes tend to bulge from the exertion of effort and the anticipation of making contact. Of course, success of this endeavor is depicted by a different glyph altogether. Successive curvature of the spine seen among aged men was once speculated to be a result of this behavior, a belief correlated by women at a younger age becoming bent over due to constant positioning assumed by the「female role」(旦), but is now understood by scientists to be more attributable to a calcium deficiency.
　「Autofellatio is the act of oral stimulation of one's own penis as a form of masturbation. It is physically possible for men who have sufficient flexibility, penis size or a combination of the two to perform autofellatio. …It has also been observed, simultaneously with manual masturbation, among Cape ground squirrels. Egyptologist David Lorton says that many ancient texts refer to autofellatio within the religion of Egypt, both in the realm of the gods and among the followers performing religious rituals.」

　「Plants with sun big」: the Sun appears bigger when nearing the horizon just after sunrise and before sunset, although in reality an optical illusion of perspective comparison. A「sunset through many plants」as DUSK, SEE-THROUGH, SUNSET meaning to sink out of sight, disappear, cease to exist with a DOWNWARD MOTION. The Sun actually setting into a bunch of plants and not beyond the horizon as the planet revolves is an IMPOSSIBILITY and WILL NEVER OCCUR, and only a FOOL, IDIOT, IGNORAMUS, MORON, DOLT, IMBECILE will believe that the Sun literally rises and sets among trees and plants, or that there is a 'special land' from which the Sun rises and/or sets. Note that humans were tortured to death during the age of the Spanish Inquisition for not professing a belief that the Earth was positioned at the center of the Universe, and that was not so long ago.
　Further note that「morning, sunrise, imbecile」as an element is depicted with「Sun amidst one top plant and one bottom plant」(屮, 龺) while「evening, sunset, imbecile」in this glyph is depicted with「sun amidst two top plants and two bottom plants」(茻) almost as if some plant growth occurred during the daylight portion since sunrise, or so the scholars tell us.
　Without a doubt, the Irish also have knowledge of their own to pass along in these trying times:「Masturbation will not spread coronavirus, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.」Nonetheless and regrettably, unlike in dynastic China, it must be undertaken alone to truly be a preventative countermeasure but still achieve the desired result with some degree of safety.

　The Dutch, too have the same solution—it seems masturbation has become mainstream in the media the world over due to the coronavirus (it has always been 'the main stream' in reality, albeit covertly for most folks):
　「'Don't have sex with your partner if they have been isolated because of (suspected) coronavirus infection,' the RVIM says. 'Sex with yourself or with others at a distance is possible (think of telling erotic stories, masturbating together).'」

　Needless to point out perhaps, but Chinese shamans from antiquity hit upon the same solution as a pandemic preventative countermeasure, honed for ultimate client satisfaction by utilizing naked females with no-longer-integrated feet as masturbatory sex buddies available for short-term rental with erotic visualization of live prepubescent female genitalia engaging in autoerotic stimulation herself, as a solution to the same problem facing us now, but in pre-Internet days.
