Different romantic and sexual orientations.
"A sexual orientation is whether you feel a sexual attraction to another person or not, and who you are sexually attracted to. Sexual attraction is a desire to have sexual relations with another person and/or vivid sexual fantasies of said person. Sexual attraction should not be confused with aesthetic attraction."
"A romantic orientation is whether you experience romantic attraction to another person or not, and to whom you experience romantic attraction. Romantic attraction is a desire to be close/intimate with another person, but is not necessarily sexual."
