Polyromantic
Polyromantic means that a person is romantically attracted to people of more than one gender. The term can also be used as an umbrella term for biromantic, panromantic, and/or omniromantic identities, describing romantic attraction that is not limited to only one gender.
The term does not say anything about sexual attraction; it refers only to romantic feelings and relationships. Depending on the person, being polyromantic can be experienced in different ways, for example with clear preferences, changing attractions, or little emphasis on gender categories.
