「Loose dripping orifice, short leg rod in vulva with meat downward thrusting in crotch」describes a BONOBO and the NAKED APE: a human being, the so-called 'higher' primates. Most bonobos kept caged in zoological gardens eventually masturbate most of the time, but perhaps only do so as a result of boredom. Non-captive primates (including human being in that group) masturbate as well:
　「Masturbation appears to be particularly prominent in several non-human primate species, but is largely restricted to Old World monkeys and apes, while remaining rare in New World monkeys and absent in prosimians. In the few New World species that have been observed masturbating, ejaculation during masturbation is exceedingly rare. While ejaculation has been observed during masturbation in nearly all Old World anthropoids (i.e. 91% of cercopithecoids and 100% of hominoids), ejaculation from masturbation has only been observed in one New World genus: Brachyteles, or muriqui (spider monkeys. N.b. Brachyteles, despite classification as a New World genus, are unique among New World primates in their maintenance of a highly interactive/cooperative, bonobo-like social structure). Importantly, there was no significant difference in masturbatory practices in captive or semi-captive and wild primates, insinuating autoeroticism as naturally occurring in many non-human primate species. Bouts of masturbation occurred most frequently in species possessing multi-male multi-female breeding systems and those with large testis volume relative to body size.」
　「Though relatively poorly characterized, female masturbation has been observed in some non-human primate species, including chimpanzees, orangutans, golden lion tamarins, and Goeldi's monkeys, though the latter two (New World) cases were exclusively observed in captive groups. This practice often took the form of self-stimulation of the clitoris and perineal region using either the fingers or tail. In some rare cases, orangutans of both sexes have been observed fashioning leaves or twigs for use in genital stimulation. This is significant, as the use of objects to aid in masturbation appears exclusive to Old World apes and humans, and may reflect a unique cognitive component of the behavior. It should be noted that male dolphins, which demonstrate remarkable cognitive abilities, have also been observed utilizing objects such as the tank floor and the bodies of other males for genital self-stimulation.」
　「…Masturbation is a common practice in all human populations. Though some form of autoerotic genital manipulation may likely be universal across individuals, sufficient data does not currently exist to stake this easily-falsifiable claim.」

　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.
