Boar, pig, or hogs, all animals of the same variety, or that all behave alike. Elements of「animals with hair」that are like「conspicuous homosexual men」in some way, perhaps such as, that pigs eat in the same place as where they defecate, and homosexual men generally perform both oral and anal sexual acts? apparently however, swine, boars and pigs do acquire 'bad habits' (per pig ranchers and farmers) and require supervision of mating to overcome or prevent the development of 'abnormal behavior' (for pigs, say the ranchers and farmers). Often when young boars are 'run together' they develop the habit of「serving into the rectum」of another animal. Other, less common behaviors such as masturbation do occur, and when boars continue these habits they should be culled (or for human beings in ancient China, perhaps it was「time to move to the big city」).
Boars that may have been isolated from females will require a period of adjustment and social contact with females prior to being 'worked' due to an acquired affinity for other boars, and for rectums of other swine, say the ranchers and farmers.
Note that neither homosexuality, nor swine for that matter, were considered abnormal in China, but that mixing homosexual behavior with swine was likely a crime of some sort…see the「crime」glyph (犯) for details…but tupping a ewe's vagina was recommendable and praiseworthy behavior for any manly man, as was habitual anal sex with a human female, the hallmark of an「accommodating woman」(嬖). Moreover, anal sex with that ewe was only considered an「error」(差) due to arriving at a nearby but different orifice…clearly, anal behavior was (is?) not restricted to homosexuals, but seems to be one distinguishing quality.
Some browsers will not display this glyph using certain fonts…the actual glyph may possibly be seen within other glyphs as an element.
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.
