Analterous

Nonalterous, also known as a-alterous or analterous, is an orientation where one does not experience alterous attraction. Nonalterous people may still engage in activities typically defined by alterous attraction, such as strong emotional connections or relationships.

The opposite of nonalterous would be alloalterous, where one experiences alterous attraction.

History
The term alterous attraction was introduced in 2015 and it is assumed that nonalterous was introduced shortly afterwards since it has been used in a-spec communities for several years.

Flag
The nonalterous flag was made in July of 2021 by Fandom user foreigntoolmaker. It keeps the pink and yellow from Tumblr user Alterous-Albatross's original alterous flag" to represent alterous attraction, but adds blue to represent alterous crushes (meshes/hushes), white to represent being valid without experiencing alterous attraction, and black to represent being nonalterous.
