I've looked everywhere for this story and can't find it. I hope you can help.
What I can remember of it is that a group of scientists developed a an airborne virus or something that, once they spread it around the globe, made all women need to swallow or take in a dose of semen every 72 hours or else they'd die.
No one could figure out how to reverse it so all of civilization had to completely recalibrate to aid in the survival of women. Which resulted in men having harems of women who craved their semen. There were schools for girls to learn how to please men up until they were of age to join a man's harem. And this virus also caused a Darwinian disappearance of unattractive women and lesbians.
This Tory was really hot, well-written, and just overall compelling to read, but for the life of me I couldn't find it anywhere. Please /r/eroticstories, you're my only hope.
