I agree, it is far more then just about sex and frequency. Willingness to have sex is BARELY a beginning. I know my own wife is willing to have sex because I "need" it. I HATE this. True passion requires BOTH partners to love and desire sex on a roughly equal level. I think what it boils down to (for some people) is that they want to be "Wanted" and not "Needed". How do you express "Want"? You do so with sexual desire.
