Aroflexible or Flexible Aromantic refers to those who are mostly aromantic and occasionally experience romantic attraction; however, the attraction they experience is so little and/or rare that they consider themselves aromantic with fluidity. This would fit the "little to no attraction" definition of aromanticism. It is sometimes given the same definition as dark greyromantic.
Another definition is when one is aromantic,but is willing to experiment or try romantic love or relationships.
