Moving in wave-like motions UNDULATING, limbs bent at the knees and elbows. Flaccid and flapping like a loose windsock all tuckered out, shrunken and emaciated:「person's hair resembling the bent limb branches of a cedar」dripping with pollen gametophytes from androecium (male reproductive structures of plants). All should take note that while undoubtedly giving a great deal of pleasure, masturbating into long hair causes serious ENTWINEMENT problems as described by numerous other glyphs that fortunately are fully treatable after thoroughly drying all emissions…later, combing out the encrusted flakes resembles a cedar branch releasing pollen, but the long-haired person must walk around with s-s-spunky hair for quite a while: perhaps the inspiration for PUNK HAIRSTYLING, or that little Something About Mary…
　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.
