well it means it takes place in a timeline where every president of america has been a woman, in a timeline where there were men's suffrage marches,
all the people who died in childbirth in our timeline survived in that one, because none of them could even get pregnant
think of every renowned manslut. in this world, the're the ones who can get pregnant. Bill Clinton, Casanova, Hugh Hefner, Gene Simmons, Charlie Sheen. How does the risk of getting pregnant influence their decisions? That could change history.
what about sexual attitutdes. Lots of people IRL think sex between girls doesn't count since there's no penetration, and don't consider it cheating if their GF is fucking girls on the side.
Is that retained, because its still men who do the penetrating, or is it flipped, because it stems from an attitude in the dominant sex of the culture only being able to recognize other members of the dominant sex as competitors? In this universe do chad girls just go 'that's hot' when they find out their BF has being enjoying a bit of sodomy with Tom from pottery class, confident that its harmless because there was no vagina involved so wasn't real sex?
