Analogy/ Love

"He shut his eyes, he shook his head with the gesture of a dog shaking its ears as it emerges from the water" (pg 144-145).  This is an example of analogy.  It is comparing the way John was shaking his head toward his thoughts to a dog shaking its ears.  I think that John was shaking his head because he feels that he may love Lenina.  Since Lenina was asleep, he was very tempted to touch her or kiss her.  However, he resisted from the temptation and just stepped away once Bernard came back.  John is afraid to feel something for Lenina.  This is because he knows that Lenina and Bernard are something special, and he feels it is wrong what he is feeling!  I actually am not sure if at the end if Lenina with end up with John, Bernard, or possibly someone else because both John and Bernard treat Lenina very well!
