「Adult male with goal eyeing copulation」ought to be recognized by everyone sooner in life rather than later as THE ESTABLISHED RULE, what is CUSTOMARY, the STANDARD BEHAVIOR, with thoughts SCHEMING to do so, the CONVENTIONAL way of behaving, so prepare oneself accordingly.
　「Looking at adult male」describes the official government stations at gateways into the prostitution quarters where inspections were conducted in order to restrict entry to those not meeting health standards. Related glyph (䂓) depicts permitting the inspection of a male's genitals prior to engaging in sexual activity as a matter of AN ESTABLISHED RULE, CUSTOM, STANDARD and plain good sense with etiquette, to see if the condition MEASURES UP TO CONVENTIONAL STANDARDS of cleanliness and good health. Failing the inspection relates to ADMONISHMENT and to later SCHEMES for bypassing or skirting future inspections.
　Perhaps depicts the coming of age for a male that is at puberty in many cultures, becoming an「adult male」that entails「looking, watching, observing」if the man is meeting a SET OF CONVENTIONAL STANDARDS within society, to「see if he measures up」and be granted full rights. Note that the legal status of minors in most societies, such as the United States of America, is akin to mental deficients, idiots,「loonies」(literally,「Moon watchers」), the insane, and criminals, and as such are not held responsible for many of their own actions…but this legal theory is still evolving. Meaning of a DRAFTING COMPASS connotes the young man with his legs spread wide and turning around for all to inspect his male member, creating an image that resembles a drafting compass, and his MEASUREMENT…or, the glyph simply resembles that particular measurement tool.
