Monoromantic refers to someone who is romantically attracted exclusively to a single gender. Monoromantic refers both to gay people, straight people, and anyone else who is attracted to a single gender. It is typically used by m-spec people to refer to anyone who is not m-spec (with the exception of a-specs, who are attracted to zero genders). It is similar to the terms cisgender or alloromantic in that way. It is commonly used when talking about monosexism; the prejudice against biromantics and other m-spec identities.
The opposite to monoromantic is multiromantic. The sexual counterpart to monoromantic is monosexual.
