There are many different types of kisses. There's a passionate kiss of farewell - like the kind Rhett gave Scarlett when he went off to war. The kiss of I-can't-really-be-with-you-but-I-want-to-be - like with Superman and Lois Lane. There's the first kiss - one that is gentle and hesitant, warm and vulnerable. And then there's the kiss of possession - which was how Ren kissed me now.
