History Main / NoHeterosexualSexAllowed

* In Joe Haldeman's ''TheForeverWar'', the Earth's government officially encouraged homosexuality ("homolife") to promote PopulationControl, which had caused worldwide food wars; eventually, they eliminated heterosexual reproduction altogether and employed cloning to perpetuate (and change) the species. With the time dilation the protagonist experiences he eventually ends up as one of the few heterosexuals and is regarded as aberrant.

* In one episode of BarneyMiller, a man claiming to be a time-traveller is arrested. He says that in the future (he doesn't specify when exactly), the government encourages homosexuality as a way of keeping the population down.

* While it's not exactly encouraged directly, the wizards of Literature/{{Discworld}} (who are forbidden to reproduce as a means of preventing [[MagicalSeventhSon sourcery]]) apparently ''are'' willing to tolerate homosexuality among their fellows.

* In "A Brother's Price" by Wen Spencer, heterosexual sex is allowed, but next to impossible for unmarried women, as men are so scarce. This leads to female prostitutes who try to appear as masculine as possible so attract female customers.

* ''Literature/FromTheNewWorld'' uses the trope, but only among children and not for population control reasons. Instead, it's expected that teenagers below a certain age will have sexual relationships within their own gender until they're teamed with a student of the opposite gender "for schoolwork purposes," at which point they're permitted to enter into opposite-sex relationships. This is done because the fact that EveryoneIsBi is part of Kamisu 66' social control system, or as one infodump puts it, "the society of love."

* In LRonHubbard's ''Mission Earth'' dekalogy, the Rockecenter Corporation (which secretly controls the world) promotes homosexuality as "psychiatric birth control."

* While it's not exactly encouraged directly, the wizards of Literature/{{Discworld}} (who are forbidden to reproduce as a means of preventing sourcery) apparently ''are'' willing to tolerate homosexuality among their fellows.

* ''TheOnion'', parodying opposition to same-sex marriage rights being billed as "protecting traditional marriage" ran an article called [[http://www.theonion.com/articles/massachusetts-supreme-court-orders-all-citizens-to,1135/ Massachusetts Supreme Court Orders All Citizens To Gay Marry]]

* In ''IWillFearNoEvil'' by Creator/RobertAHeinlein, the government doesn't quite go so far as to forbid heterosexual sex, but they strongly encourage homosexuality for this reason.

* In ''IWillFearNoEvil'' by RobertAHeinlein, the government doesn't quite go so far as to forbid heterosexual sex, but they strongly encourage homosexuality for this reason.

* In [[AClockworkOrange Anthony Burgess']] ''The Wanting Seed'', heterosexuals are discriminated against while homosexuality ("It's sapiens to be homo!"), self-sterilization, and eventually even cannibalism are responses to overpopulation and limited resources.

To try to solve an [[PopulationControl overpopulation problem]], governments (in fiction and [[TruthInTelevision real life]]) may limit the total number of children a person or couple can have; enforced with sterility, abortions, infanticide, criminal punishment, or social stigmas. Less frequently, a {{dystopia}} may try to reduce (or eliminate, if other methods like [[GattacaBabies cloning or bottle babies]] are in use) pregnancy by [[NoSexAllowed banning sex]] altogether. However, the absolute rarest version of this trope is where the PowersThatBe encourage (or require) homosexuality in some or all of the populace in order to keep the population down.

[[AC:{{Real Life}}]]
* The Hungarian socialist party did a pretty good job of discrediting heterosexual sex for similar but less global purposes. Their attempts were mainly disguised as a gay rights campaign, but also included promoting single lifestyle, and declaring sexual differentiation to be HarmfulToMinors.

This is different from a CastFullOfGay, which is just a story where the majority of characters happen to be gay, or tropes such as EveryoneIsGay and HetIsEw which are about fanfiction (where straight characters in original works are turned gay for the purpose of the story).
