How we cite our quotes:
[Bella to Edward:] "Of course not." I flushed. "I told you I've never felt like this about anyone before, not even close." (14.279)
This is both Edward and Bella's first romantic relationship.
[Edward to Bella:] "I know. It's just that I know other people's thoughts. I know love and lust don't always keep the same company." (14.280)
Edward knows sex and love don't always go together. In this case, Edward and Bella have love without sex.
[Bella:] "Your human instincts…" I began. He waited. "Well, do you find me attractive, in that way, at all?"
He laughed and lightly rumpled my nearly dry hair.
[Edward:] "I may not be a human, but I am a man," he assured me. (14.294-296)
Bella wonders if Edward is sexually attracted to her. She doesn't want to only be appealing to Edward's "vampire instincts" (smelling delicious).
