「Self conferring」describes the trunk of an elephant, an animal with a very large NOSE, by which it feeds itself, pulls down vegetation, picks up items, sprays itself when bathing, and likely performs other self-conferring functions.
　「Self」with「plugging orifice on pedestal conferred as reward.」…frankly, in cases such as these with the gifted orifice raised off the floor, many early humans should and would have taken a sniff first (much like a dog uses its SNOUT), prior to engaging it in other ways: USING ONE'S NOSE AND SENSE OF SMELL.
　Both boar and dog snouts are euphemistic of a human male's erection: long and hard with an orifice at the tip: swine use their snout to burrow into soil seeking mushrooms (imagine that) and dogs poke their nose into an anus in order to identify the scent of the anus' owner for later reference. Other analogies remain fundamentally for the reader's fertile imagination.
　「Self, cerebral frontal lobe」and「confer」: the frontal lobe is where sensory information such as smells are processed and stored into memory, and the manner in which smells are sensed and「conferred to self」is via the NOSE. As sometimes「plugged or filled orifices」that are openly displayed on the front of most everyone's face, as if set upon a「high pedestal」above the ground. That there are two such orifices side by side separated by the fleshy wall of the septum is significant, since that shape is also found at the perineum and its two adjoining sometimes mucus-laden orifices, the point of what was conferred as「the prize (畀).」
　Some modern fonts use「self with plugged orifices and two hands wringing」(廾) perhaps blowing one's NOSE or using one's fingers to reopen one or both of these「plugged orifices.」…people and bonobos have indeed done that for a very long time, removing 'boogers' as those chunks of dried mucus in the NOSE that constantly bedevil the「cerebral frontal lobe.」So named since one in needs a「bougie」to ream and clean the passageways ('bougie' means 'to restart a flow').
　「Evolutionary biologists have traced the origins of masturbation to ancient primates that predate the first humans by tens of millions of years. The findings emerged from what scientists believe is the largest dataset ever compiled on the activity, and confirm that humans arose on a branch of the tree of life replete with self-pleasuring predecessors. 'What we can say is this behaviour was present around 40m (40,000,000) years ago, in the common ancestor of all monkeys and apes,' said Dr Matilda Brindle, the lead researcher on the study at University College London. 'It's not that some species woke up one day and started doing it. This is an ancient, evolved trait.' '…This is such a common behaviour across the animal kingdom, I find it absolutely baffling that nobody has researched it before,' said Brindle. 'For people who think masturbation is wrong, or unnatural in some way, this is perfectly natural behaviour. It's part of our healthy repertoire of sexual behaviours.'」

　And as a fact that perhaps only zookeepers are aware of today, the nose is generally a fine place to readily locate a source of mucus needed for lubrication when bonobos or other animals, such as human beings in the past, start to perform some「self-conferring of the prize, getting some self-booty.」…both male and female bonobos have learned to blow snot into a hand and use it to begin masturbation, and this technique is deliberately taught to the young. See 齆 and 鼽
　While no longer a major concern for most of us today, one fast and sure path into a person's frontal lobe is via the NOSE, important knowledge for a society of hungry cannibals wishing to「confer frontal lobes, brains」as the group's supper (and this fact may have caused some scholars to understand 田 as meaning a head filled with brains).
　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.
