「Feeling or spewing penis with wild screaming in cavern」meaning SHOULD AND MUST REACT. A RESPONSE and REACTION to some stimulus, a reasonable cause for COMPLYING WITH THE RULES. Elements are「palming erection, cavern」with「person and courtship display stance」over「appendage spewing drops」…but the inner elements (雁) together also refer to「wild screaming, sounds of geese or goosing.」Most likely refers to human vocalization and hollering as do excited bonobos during clustered sexual activity that apparently evolved exactly for the purpose of attracting additional mates during copulation sessions, meaning SHOULD AND MUST REACT, a REACTION and RESPONSE, AFFIRMING that something must be now be performed.
　Perhaps refers to washing after sexual contact in order to mitigate the spread of disease and infection as an inviolate law, SHOULD AND MUST do, COMPLY WITH THE RULES…the lowermost glyph element is often carved into what are today used as ritual hand-washing facilities at shrines and temples in Japan.
　Also seems to refer to actions IN PROPORTION TO, and CORRESPONDING TO「venom-spewing appendage」or「feelings, heart, mind」inside the tribal「cavern」: SHOULD or MUST REACT with a RESPONSE, I AGREE SOMETHING MUST BE DONE immediately about that problem.「In cavern」with「wild goose screams」and「feelings, spewing appendage」would necessarily elicit some sort of REACTION and RESPONSE when heard, such as when hearing the terrified screams of another person after sighting some other diseased appendage spewing venomous drops as the screams reverberated throughout the cave, AFFIRMING that something must be done about it, or the screaming may have been caused by medical treatments, reaming the urethra with a bougie to remove gleet, a painful procedure that caused blood-curdling screams as the curdled blood was being extracted.
　Many, if not most, anthropologists understand that bonobos today exhibit the behavior of early humans, and modern humans, too:
　「Sometimes females would rather GG-rub [genital-to-genital] with each other than copulate with a male. Parish filmed a 15-minute scene at a bonobo colony at the San Diego Wild Animal Park in which a male, Vernon, repeatedly solicited two females, Lisa and Loretta. Again and again he arched his back and displayed his erect penis—the bonobo request for sex. The females moved away from him, tactfully turning him down until they crept behind a tree and GG-rubbed with each other.」

　「The bonobo, an African ape closely related to humans, has an even bigger sexual appetite. Studies suggest 75 percent of bonobo sex is nonreproductive and that nearly all bonobos are bisexual.」　[　https://www.mentalfloss.com/posts/weird-animal-sex-facts 2023-05-44　]　
　「Like humans but unlike chimps and most other animals, bonobos separate sex from reproduction. They seem to treat sex as a pleasurable activity, and they rely on it as a sort of social glue, to make or break all sorts of relationships. 'Ancestral humans behaved like this,' proposes Frans de Waal, an ethologist at the Yerkes Regional Primate Research Center at Emory University. 'Later, when we developed the family system, the use of sex for this sort of purpose became more limited, mainly occurring within families [i.e., incest]. A lot of the things we see, like pedophilia and homosexuality, may be leftovers that some now consider unacceptable in our particular society.' 」
