I don't know if such books exist but

In The Shore of Women, the society is female-only and they are all gay. The novel however continues with braking that norm.
Also there is this website that I think is little known - Filter by Female/Gay worlds, you get 30 books.


Blindness is an example of an illness inflicting everyone. I think you might need to look into similar literature, or even dystopian and post-apocalyptic for this type of setting.
In Lauren Oliver's Delirium everyone is "considered" ill and at the age of 16 they are being cured of "love". A similar theme but more adult book is This Perfect Day. Also see The Children of Men

However I don't think this is what you were requesting. As those books explore how societies are trying to cure themselves, rather than accept and live with their infliction.

If you consider infertility a medical problem, then Margaret Atwood's The Handmaid's Tale fits. The Handmaid's Tale

Another book in which being born with medical problems is "normal" is Wither by Lauren DeStefano. Wither

Ethan of Athos by Lois McMaster Bujold. It's an all-male world.

In The Left Hand of Darkness by Ursula K. Le Guin, a human emissary visits a planet inhabited by a hermaphroditic species.

Ursula K. Le Guin also has a series of stories about a planet (Planet O) with an elaborate four person hetero- and homo-sexual marriage system (sedoretu), including the title story (really more of a novella than a short story) from A Fisherman of the Inland Sea (or The Found and the Lost: The Collected Novellas of Ursula K. Le Guin ), "Unchosen Love" and "Mountain Ways" (which can both be found in The Birthday of the World and Other Stories. I vaguely remember another story about the Ki'O but can't come up with it.

Probably not what you're looking for, but the second half or so of The Forever War would count. It's about a war with an alien race that starts in the 1990s but is waged with ships that move at relativistic speeds. The book follows one main character over hundreds of years. His first mission takes a year or so as far as he's concerned, but when he gets back to Earth over forty years have passed.

When he gets promoted after a few missions he's put in charge of new recruits who grew up in a changed society in which everyone is born gay and heterosexuality is viewed as an aberration or even an abomination. English is no longer spoken much on Earth but is still used as the main language in the military, so the MC at one point muses that he's in charge of a group of trained killers who think he's a sexual deviant and have been forced to learn a dead language just so he can order them around. Not the most comfortable position. It's all told from his point of view, though, so it probably doesn't go into as much detail as you're looking for.

Mother of Demons

From description: An outcast with a perversion (she liked males);

[Heather]

The Gaean Trilogy by John Varley has a group of witches that use men only to get pregnant, then give the men the boy babies, and keep the girls. Loving males is forbidden. There are also creatures that use a different form of reproduction that requires one of those witches to approve it, and start the process.

For something light, I'd suggest Boy Meets Boy,
a lovely book where being straight is not the norm, and The Rest of Us Just Live Here, where almost every character would not be considered normal in our daily world. Both great books, too!

There are a lot of sci-fi books set in a future or otherwise advanced society where heterosexuality and/or fixed gender are not considered the norm. Iain M. Banks' Culture books are a good example - in The Player of Games, the protagonist's friend calls him "strange" because he's never slept with a man or changed sex. Similarly, Arthur C. Clarke's Imperial Earth and The Songs Of Distant Earth.

I'm currently reading The Stars Are Legion and it's all female society. You can certainly feel the lack of male population. I often think how different this book would have been if males existed and how much the power play would be different.

However I've been thinking that all these books simply create specific setting with gender reversal or creating matriarchal/female-exclusive societies. They don't really concentrate on the gender/sexual issues that we have in our society. It wold be nice to read a book where the roles are reversed.

Btw have a look at these video sketches.
