[M4F] It's A Man's World, But Space Belongs To The Women

In the near future, humanity has made leaps and bounds in space travel with the Johnson-Tanaka Drive.

The Tanaka near-light-speed (NLS) Drive technology was technically usable for a long time, but it held a terrible cost- the gravity made it totally liquefy humans, rendering it a useful scouting tool for the first forty years after its inception, humanity keenly looking on as the probes that ventured outside the solar system discovered Goldilocks planets, asteroids rich with materials, and vast deposits of natural gases just floating around in space.

Then, an ingenious chemist called Dmitry Johnson, the son of a Russian climate refugee and American business mogul, invented what is now lovingly referred to as 'jump juice'; a serum injected just before hitting NLS to avoid the liquefication problem by a technology sufficiently advanced to be described as magic.

This immediately opened up the stars to humanity, with asteroid mining triggering a second boom of commerce, and outposts on many planets outside of our solar system starting to put down roots. It was the dawn of a new era of human civilisation, narrowly escaping the confines of the Earth as climate change slowly rendered vast swathes of Australia, Africa, and America uninhabitable, underwater, or perpetually on fire.

The only issue?

Some genomic fault in the Y chromosome makes the jump juice that's needed to survive NLS lethal to men, rendering the men totally mush. Even their sperm was unusable, the proteins totally unbinding, making any sort of artificial insemination impossible.

So, all the miners and space ships are staffed almost entirely by women- men were landlocked, doomed to live out their last days on the planet that they had destroyed. A couple lucky ones managed to buy tickets aboard The Golden Cage fleet, generation ships that were en-route to the distant budding colony of Tanaka, a city founded on Eroad, a goldilocks planet that was several hundred years away; the men would die aboard, but those floating fortresses of opulence were admittedly the largest genomic pool available.

Save for a few, lucky men with the CX-9 gene that could stand the jump juice.

They were as rare as hen's teeth, but they existed- in a less advanced age, they'd be old wive's tales, rumours of virile young studs that roamed the streets, with a bevy of enchanted girls hanging off of them. Talk of a handsome man wearing a wig to blend in as he made his way to the Tanakan Prime Minister's chambers, for some sort of 'meeting'. Of course, information traveled differently, in a post-NLS age; the age old question of whether a pigeon with a USB strapped to it was once more brought into the conversation, and the decision was an emphatic 'yes'; radio waves were clunky, slow, and prone to degradation. Ships taking on board a disk of the local net was cheap, if somewhat laggy, and prone to getting lost. So the talk of men spread less like wildfire, and more like a flashstorm; areas would suddenly get the news, and be ablaze with chatter, Brazilian waxes, and fantasies, all for them to realise a week later that the man had already passed through two weeks before they received the message.

Hi there! Thanks for sticking through all that, it's certainly a lot of exposition for what is admittedly a very simple plot; there's one guy in space. I'd be very keen to play the adventures of the few men that are blessed with the right genes opposite somebody that's happy to play the women that he encounters, but recognise that that might be as rare as the men that I've described! If you, dear reader, are not interested in that, but are interested in the world, I would love some help world-building this into something more concrete- I'm imagining the technology to be similar to The Expanse; there's no cryo, no FTL, but there's plenty of tech, established colonies, and there's the jump juice that lets them travel close to the speed of light- only difference being that the jump juice is poison to most men.
