Many element combinations are possible with this glyph. Perhaps the clearest interpretation is「prostrate with rod up copulation」as what must occur FIRST, what PRECEDES and THE INEVITABLE FUTURE:「chattel meat herd assets with erect penis」and「inform about copulation」both meaning doing so AHEAD IN TIME, BEFORE anything else, the senior members of the harem teaching and informing the junior members about the lord and how to service him as desired. TO ANTICIPATE and TO FORESTALL problems, what PRECEDES the remainder, the role of a teacher, the prime information needed by every human being as「the facts of life」in order to protect and prepare for THE INEVITABLE FUTURE, to enable good decision-making for the remainder of one's life using facts and not bullshit fairy tales or deliberately concealing the truth to somehow protect innocence—unsuspecting gullible and naive innocents are quickly devoured by predators, become diseased with rotting flesh infections, and in short: either die young or are impregnated early. Glyph also can refer to WHAT IS AHEAD, WHAT IS APPROACHING AND WILL SOON OCCUR after a person obtains「information about copulation.」
　「Withdrawal, pull-out with copulation」meaning AHEAD IN TIME, BEFORE anything else, TO ANTICIPATE and TO FORESTALL, what PRECEDES the remainder. An instruction to pull out and withdraw AHEAD OF TIME and not leave a seminal deposit that can cause future problems and/or pregnancies…COITUS INTERRUPTUS as a method of contra-conception control of NOZZLE spurts, one of「the facts of life.」
　Elements may be「head」of「mushroom」and while there are at least 14,000 varieties of mushrooms, generally the cap, or「the head of the mushroom」the TIP, top EDGE, appears FIRST, AHEAD IN TIME, BEFORE anything else, and PRECEDES the remainder of the fungus…mushrooms are also a food source of vitamin D (being in the Sun's shine is another), contain high levels of antioxidants, contain selenium that is essential for preventing cancer, increase metabolic rate, and strengthen the immune system TO ANTICIPATE and TO FORESTALL health problems.
　A「head」with「ground-breaking」techniques as the FIRST PERSON to do or try something, BEFORE anyone else has thought of doing so, TO ANTICIPATE and TO FORESTALL competition. Having a「head」for「soil copulation」as being the intended DESTINATION, and literally in that case as NOZZLE, but is also a frequent cause of contracting hepatitis and other disease, and will FORESTALL, prevent, hinder most further action, another「fact of life.」
