Love and Lust may appear to be polar opposites, but they can coexist. In fact, it is one of the best things that can happen hen they do! Sure, you can love someone, but not 'in that way' and you can lust for someone you have no intention of having any feelings for. This is a given.
However, when you get into a certain kind of relationship and the stars align just so, you can have that perfect thing: Loving someone, being in love with them and lusting after them! Lust with love is a wonderful thing. Both of the human desires are covered -- the desires to be both emotionally and physically intimate, when in unison, make a beautiful union.
