One of my projects has been developed around the idea that humans in the future visit an earthlike planet in Andromeda. The planet is populated with humanoid creatures that are “well endowed.” Ex: the ‘gender’ that gestates the baby has large nutritional organs. The other gender has other attributes. There is a third gender, one without any defining ‘characteristics’.
When humans arrive at this planet, some aliens are very welcoming. They see the humans as interesting, like a pet, as in the original Planet of the Apes with Roddy McDowell. Or, as a nuisance, but a possible food source. Both the friendly and the adversarial aliens see the humans as a source of new technology. So, there are different power struggles and motivations. So far so good. The humans are hapless explorers, not directed by an organizing principle as in ST-TOS, more along the lines of Arthur Dent (though their travels are not quite that incidental). Human travel became possible through (advanced) Space X rockets, and some people took it as an opportunity to get off earth They found this planet in the Andromeda system.
Here’s my problem. I am trying to integrate components of social dominance into the story, (inspired to make societal commentary on current events). In numerous Earth countries, notable figures have recently risen to power through bullying and mysogyny; other notable figures are widely lauded for their attractiveness. Let's not get into details. (I mention it only to provide motivation for my world.) Suffice to say, I took on this project to create a ridiculous scenario in which dominance is asserted through ludicrous, physical means.
On earth, flashing is a means of suggesting dominance (although that is lesser to other reasons.) The problem I am having, is I cannot devise a compelling reason why these aliens would flash humans. I don’t think it makes sense that they would do this to ‘impress’ humans. The organs are too different. Maybe they can’t help it; it’s instinctive. (I’ve established that the aliens have a unique courtship, like a peacock spreading its tail.) I am drawing a blank. Any help is welcome.
