How we cite our quotes: (Chapter.Paragraph)
Quote #1
[Trip] received letters emblazoned with ten different sets of lips (the lines of each pucker distinct as a fingerprint). He stopped studying for tests because of all the girls who came over to cram with him in bed. He spent his time keeping up his tan, floating on an air mattress around his bathtub-size swimming pool. The girls were right in choosing to love Trip, because he was the only boy who could keep his mouth shut. (3.41)
Trip Fontaine, the sexiest guy in school, has girls throwing themselves at him left and right. He doesn't have to work at school anymore, because he can exchange sexual favors for study tips. The sexually inexperienced boys see Trip as a love god who they'll never be able to measure up to. They also point out one of the real dangers of teenage sex—boys like to brag about their conquests. Trip, to his great credit, doesn't.
Quote #2
He didn't understand how she had bewitched him, nor why having done so she promptly forgot his existence, and in desperate moods he asked his mirror why the only girl he was crazy about was the only girl not crazy about him. For a long time he resorted to his time-tested methods of attracting girls, brushing his hair back as Lux passed, or clomping his boots up on the desktop, and once he even lowered his tinted glasses to give her the boon of his eyes. But she didn't look. (3.49)
In Lux, Trip finally finds a girl who doesn't just jump him at first sight. Perhaps the challenge, or the unexpectedness of her coolness, is what makes her irresistible to him. It wouldn't be the first time that unrequited love just made the beloved that much more attractive.
Quote #3
He thought about Lux getting ready for bed, and just the idea of her holding a toothbrush excited him more than the full-fledged nudity he saw in his own bedroom nearly every night. (3.57)
Trip is used to having sex. He has a parade of girls and women coming through his home, attracted by his good looks. But since he can't have Lux, every single, mundane thing she does is attractive to him. The toothbrush, that most unsexy accessory, becomes sexier than full frontal nudity. It's the mystery that's exciting.
