In Chinese, conveys meanings of OUTSTANDING but at times in a negative manner, so perhaps STANDING OUT in a crowd for example might be more applicable, NOTICEABLE by others…indeed, elements describe「reciprocating lateral rod segment with emphasis on erection, stretched taut bent appendage」that would likely attract some attention in most venues. In Japanese apparently, SUPERB, or a NATURAL thing, an action that occurs as a result of the inherent nature of something or someone:「rod in extended copulation」or「hand on penis」with emphasis all indeed seem to describe what is human nature, as it was then and may remain today. Although not recommended at a human gathering such as one's church potluck or while bar-hopping, male bonobos strut about masturbating in order to attract a copulation mate of either sex and of any age, which has proven to be a highly effective technique among primates for that matter.
　Perhaps「weakened」as「curling penis with hand marker stroke」or some have suggested a hand with a juicy welt that has just been stung by a venomous scorpion.
　Alternatively, looking at another reason for「weakened」and noting the marker stroke that is pointing out either the「hand」or something sticking to the back of a hand such as spurted spunk. Also possible is that the intended meaning was referring to「handling a bent, curling, diseased penis」a FAULT that was OUTSTANDING and NOTICEABLE by others during days when not everyone wore loincloths except when in the big city, but also to FEEL BITTER about something, REPROACH, BLAME for some perceived MISTAKE or an ERROR, PLAUSIBLE, NOT WITHOUT REASON, NOT UNEXPECTED, and the associated SHAMEFUL EMBARRASSMENT. Nevertheless, for what it is worth and assuming no one is telling lies, all these sometimes contradictory meanings may be encapsulated by autoerotic selfies:
　「78 percent of adults in the world masturbate, including: 96 percent of British men, 93 percent of German men, and 92 percent of American men. 78 percent of British women, 76 percent of German women, and 76 percent of American women」

　Some scholars say this glyph is a 'hand with a wart and person kneeling' while FEELING BITTER about the wart. This glyph with the「illness」element does indeed mean wart and warts do happen, are NOT UNEXPECTED and caused by a common virus, but the glyph most likely referred to genital warts 痝 as a sexually transmitted condition, human papillomavirus (HPV) since it includes the elements「sick penis」and「pubic hairs.」Perhaps due to this very glyph from China with double meanings and elements of「weakened, hand on penis」there is still extant the superstition that male masturbation causes warts.
　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.
