>>3952332That's because fujos don't fantasize about us fags—yaoi is the straight women’s fantasy of relationships. At its core, yaoi is just another genre of romance. Most tropes associated with yaoi are the same tropes associated with women’s romance novels, except instead of gendered male/female dynamics you have seme/uke. It's written predominantly by women for women and aside from the fact the cast is all male, is pretty much the same as hetero romance stories.
They do this because there’s a lot of baggage around female bodies and female sexuality. Writing a female character means being aware of her gender (making the female viewer aware of hers), whether she’s conforming to gender norms, breaking gender norms, or being objectified. Because the majority of media is made by men for men about men, female characters are subjected to more scrutiny. A poorly written male character who stars in an action movie is just a generic action hero, a female character in the same role is a mary sue or there for fanservice.
Writing about a relationship between two guys removes gender from the equation. There’s no gender dynamic between them because they’re both guys. There’s none of the baggage about their sexuality because men aren’t “sluts." So girls can write a male character fucking and impregnating their lab partner from nonstop creampies without worrying about if it's slutty. Of course, slut shaming is stupid and it'd be great if het women could say, "I like cock and have a breeding fetish," instead of living within this weird duality of the Madonna-whore complex where women are supposed to be pure, good girls who are objects of men’s desires but never sexual in their own right because that’s what whores do. But our world does have misogyny, women experience misogyny, and that means some women aren’t comfortable writing about sexuality from the perspective of their own gender or while describing their own body. Thus we get jayvik mpreg.
