This new story idea has got its hooks into me: a world where orgone-harvesting aliens have arbitrarily chastised 5% of the males between 18 and 40, turning them into chaystes.
Should there be a downside to getting turned on? Perhaps the aliens only have so many channels. So if you can just avoid sexual excitement for a few years, perhaps the thing drops off and they abduct some other sucker. This would make older chaystes somewhat suspect in the public eye. Or is it better to have "chayste" as an irrevocable identity that you just have to learn to live with?
Should people be able to tell that you're chayste?
If you can keep your chaysteness secret, then that gives us "coming out" stories, and scenes where she comes on to him, and he's trying to hide the fact he has no accessible genitals...
On the other hand, if the aliens collar their orgone donars, then that will mark them out as sexual targets for predatory young women, but also as safe playmates for intriguingly inhibited ones--
--realistically it's probably what the aliens would do, assuming they have any knowledge of humans.
What would they use? A collar or forehead crystal would be too easy to hide. How about a palm crystal, like in Logan's Run? Alien booby traps would prevent the obvious surgical solution. It would certainly be hard to hide from anybody you knew, but you could hide it most of the time in public spaces.
Perhaps it glows redder, the less orgone you produce. So, if you live the life of an ascetic hermit, it'll shine like a beacon, beckoning all the predatory females...
