Gaining popularity as the new sexuality for some genderqueer/androgyne people. Hetermosexual is the attraction to the same sex for both genders. Since genderqueers define themselves as both genders; hetermosexual means the attraction is to the same sex no matter what gender.
If a genderqueer is biologically male, but is only attracted to other men; they would be hetermosexual. Meaning when they feel feminine; the attraction to men stays, and when they are masculine; the attraction to men stays. (It's the same for females as well, obviously)
