"Heteronormativity is the belief that people fall into distinct and complementary genders (male and female) with natural roles in life. It assumes that heterosexuality is the only sexual orientation or the only norm, and that sexual and marital relations are most (or only) fitting between people of opposite sex." - Copied from Wikipedia...yes, Wikipedia, but it's the only clear source I could find.

Most of these don't really fit in with this definition. While it is true that the MC in RoE only has male love interests, that doesn't necessarily mean it is an example of heteronormativity. Besides, all the other MC's in all other books have both male and female love interests, and at the end of the day, it is purely down to the player what sexuality the MC is.
