I love how 90% of published "romance", be it het/straight/other, can be classified as idfic; it's probably one of the reasons so many "serious readers" are so condescending about it even as it outsells most everything else (Twilight = 100% idfic, although I admit, I am absolutely critical of Twilight, b/c I think it's idfic that's taken seriously as an example of an awesome relationship and I find that horrifying).
