「Changing state, doubled emphasis on rod in reciprocating motions」and「dripping, lateral emissions with rod」all describe STIFF WOOD of a masturbating male, or, a tool used by a female while performing her own pleasure sequences.
　As PIECE OF WOOD on a sick male, also meaning DEATHBED, a BIER. Successive and successful dildo use often causes relationships with males to atrophy and die as superfluous, since obviously the dildo is naturally much preferred functionally (not to mention it smells better, is fully controllable by the user, and has fewer rough spots if any at all) especially the types that vibrate. Meaning of SUPPORT FROM BENEATH is certainly applicable while on one's deathbed, or, while in the coital lordosis position with the male/dog/lord/client in the upper port as his preference and the female working on her own, or, a male simply doing his own thing…by the way, if you think these explanations are outrageous, be sure to see each use as an element in all other glyphs for confirmation and then decide.
　「Dripping flaccid-turgid rod」describes a WOODY, and perhaps one that may cause its owner to be bedridden for a time with a dose of the clap, or, permanently dead laid out on a BIER with various sphincters beginning to relax.
　In spite of vertical positioning that only Coneheads might find usable as a slar phase pad, a「rod changing states, turgid and flaccid」that often occurs when LYING ON A BED. A「rod in changing states」might need some support from beneath, especially if the「congealing」conditions are changing as a direct result of illness or infection and the need to remain lying on a BED, or in a DEATH BED, or on a BIER. Note that reference to a cone-shaped head is not coincidental.
　Per scholars, this is the left「half of a split tree」with trimmed branches used as bed legs. The strokes do somewhat resemble one-half of the glyph meaning「woody, tree」(木) split vertically. A BIER, BED apparently as the glyph「spurting stance」(䒑) or「support from beneath」(丌) rotated onto one end in order to fit within glyphs or storage areas when not in use. Formerly, only royals (usually somewhat obese) and really sick or dead folks regularly used a bed, as doing so made it easier for others to move the person's carcass when necessary. Perhaps「stiff when upright」as a corpse, a stiff with rigor mortis (爿).
　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.
