Cher's a virgin, Dionne is almost a virgin (until her brush with death on the freeway), and Tai is very experienced. In fact, Tai's "way harsh" dig at Cher during a fight is that she's a "virgin who can't drive." The fact that so much emphasis is put on being virgins, losing their respective virginities, and the art of having sex in water is just too much for a bunch of kids who are obviously just that — kids. And as an adult and parent myself, it terrifies me for the eventual teen years of my children.
The way Murray outs Christian to Cher and Dionne is equally troubling. His sexuality is no one's business but his own, and the descriptors Murray uses are completely inappropriate.
