「Palm down covering female genitalia with person palming prick」suggests HARMONY, since both the male and female are assuming a similar position with each manipulating his or her own genitals, both engaged in SAFE SEX. Clearly, when someone begins masturbating in the presence of another and continues unabated until panting heavily, then the situation may quickly evolve into one of MITIGATING CIRCUMSTANCES for anyone else witnessing and listening to such actions. Both parties might be wagging some sort of tail in the process.
　Some sources suggest a「covering」moat surrounding a「village」where birds gathered: WAGTAILS, a bird that constantly moves its tail feathers and cloaca in a circular motion, similar to a「courtship display, shaking booty.」Old versions use「loose motion」and「village, vagina」together meaning「moat」that kept villagers FEELING SAFE, with「bird walking.」The wagtail constantly moves its tail with muscles around its cloaca (a bird's combination genital and anal orifice) in a circular motion. Ornithologists are unsure of why the wagtail wags its tail, but the most accepted reason is that it may be to let predators know the bird is being vigilant, and therefore keeps the bird FEELING SAFE.
　Still others suggest this glyph refers to incestuous mother-son relations to reassure a son and help him to FEEL SAFE, to MITIGATE his stress. Note that this glyph gives no indication that the birds, villagers, or sons actually are in fact safe, only that they feel so, nor that the potential copulators are in fact harmonious, only that they feel so while still engaged in sex:「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」

　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.
