I would love to find a story about a world (not necessarily post-apocalyptic) where there are few males and women need to cum to survive. I don't care why they need it. It could be a disease that caused women's bodies to stop producing a critical protein only found in men's cum or something even dumber for all I care. I just love the idea of men being walking public cum dispensaries in a world of nearly all women. If there's already a story like that out there please let me know, my searches have come up empty.
