Unisexuality 

Male and female together as one gender.

While hermaphroditism speaks to the outward appearance of both male and female sex organs, Unisexuality is more about both genders existing at once in the same person.

unisexually appealing

A person whose personality and/or features attract both men and women, regardless of sexual orientation. Often in a class of their own.

Bro: "See that girl over there? Damn I want her."
Gay Chick: "One night is all it would take..."
Chick: "I'd go gay for her."

Everybody wants her. She's unisexually appealing.
