Bi-romantic is a term used to describe romantic attraction to more than one gender.
Biromantics aren’t necessarily sexually attracted to the same genders they’re romantically attracted to. A person can be biromantic but asexual, bisexual, heterosexual, homosexual, or pansexual.
Hetero-romantic refers to romantic attraction to only the opposite gender. Homo-romantic refers to romantic attraction to only the same gender. A-romantic is the absence of romantic attraction.
