Planet xz345 delta was founded in 2103 as a penal colony for the galaxy’s antisocial criminals. Most prisoners are male, and while their sentences are limited, there is no way off the planet when they are released. By 2230, the non-prison population is nearly 2,000,000, 86% male. Females are highly prized, and jealously protected by their husbands. But with so many men, the crime of rape is common. Thus in order to satisfy the male libido and maintain order, prostitution is legalized and bordellos are licensed with a small number of off-world whores. A single female can satisfy the sexual desires of a dozen or more men each day. The sex workers are protected from abuse, clients are protected from diseases, and the whole industry is taxed to generate revenue. While sex between unmarried people is not a crime, sex outside of marriage, with a partner who is not a whore is strictly forbidden. Although stiff fines are imposed for offenders, it does little to curb unlawful sex.
