Atomoromantic

Atomoromantic is a term for greyromantic people who have only felt romantic attraction to one person. Atomoromantic people may have trouble figuring out the gender(s) they are attracted to because they only have one experience. Atomoromantic is similar to uniromantic, however atomoromantic makes no assumptions about when or if one will feel romantic attraction again.

The sexual equivalent is atomosexual.
