Affectional orientation

Romantic orientation, also called affectional orientation, indicates the sex or gender with which a person is most likely to have a romantic relationship or fall in love. It is used both alternatively and side-by-side with the term sexual orientation, and is based on the perspective that sexual attraction is but a single component of a larger dynamic.

With regard to asexuality, while asexuals usually do not experience sexual attraction (see gray asexuality), they may still experience romantic attraction.
