Assisting anyone with an illness, including the aged, and supporting the upbringing of the young, will PRESERVE and MAINTAIN a tribe by continuation of its accumulated knowledge and experience passing between generations in all DIMENSIONS of life.
　「Threads like mating display plumage」ought to be quite beautiful and colorful, and perhaps warrant PRESERVING, MAINTAINING the cloth material…fine clothing will IMPROVE the appearance of the wearer, although it will not truly change the wearer's character or degree of knowledge of any subject other than perhaps to add a bit of arrogance and pride temporarily, some「narcissistic plumage.」
　「Ejaculation」with「courtship display」suggests that the continuation of any species will therefore be MAINTAINED, PRESERVED, and provide SUPPORT for the families of the copulating animals by having additional offspring.「Ejaculation」with「courtship display」describes a one-track minded male's goal of this entire scene regardless of which species are considered, the SINGLE DIRECTION, aim, and purpose. Also suggestive of IMPROVEMENT, since the「courtship display for ejaculation」of many species involves males battling one another, so that natural selection might cull weaker males from breeding in the gene pool…note that the weak females are often desirable as easy lays, so those strong male genes tend to be counterbalanced to some degree, leading to the meaning of DIMENSION. Fundamentally, 'dimension' is the extent, scope, or magnitude of something, and the influences of strength and weakness in both males and females during and resulting from reproduction will determine the DIMENSIONAL survival fitness of the species.
　Nevertheless, on a much more personal level applicable individually,「ejaculations of person palming prick」as a ONE-DIRECTIONAL experience may be necessary for PRESERVING, MAINTAINING the health and function of one's prostate gland and reproductive system equipment, and IMPROVEMENT particularly as the subject ages, since not everyone has the wherewithal to maintain a harem of thousands of virgins, or finds ewe attractive, or wants to risk short-term rentals of daughter-dates from brothels not knowing which spirochete demons, viruses, and bacterial agents she may have contracted during the previous hour, and so on.
　Due to their anatomical structure, birds can only walk forward, not backward and not side to side generally, walking in only ONE DIRECTION that leads to the concept of a single DIMENSION. Not surprisingly given the level of knowledge attained by the Chinese sages, elements as「bird ejaculations」also conveys these same meanings. Only a few species of all the birds possess a penile structure, which is to say, nearly all birds are 'dickless' as it were. Male birds ejaculate via the same orifice as the females: the fabled cloaca, hence in that sense「bird ejaculation」is ONE-DIMENSIONAL, so much so that it is often quite difficult to differentiate the sexes of individual birds. Male and female birds mate by joining cloacas, known as a 'cloacal kiss,' with one bird wrapping its cloaca around the other, a double-walled cloacal set that SUPPORTS and MAINTAINS the connection for sufficient duration to allow transfer of the sperm to the female.
