This reminds me of the show Californication. (I'm at the end of season 1.)
During season 1, we see the main character have sex with a girl (whom we can see naked on top of him) and is later revealed to be 16.
The main character is shocked and while he is a womanizer he says that sleeping with a 16 year old is wrong. It's an exercise to the reader if he really believes that or just chooses not to (the show is at best indifferent--because we got to see a "sixteen year old's" breasts bouncing up and down as they were having sex.) We later encounter another character who truly is bad--he takes underaged students to his house and drugs them up (though it appears that they do so voluntarily.)
The point here is that context I guess is important. But moreover, the show is hypocritical if it's trying to make us dislike the guy who drugs up underaged girls for sex, if it's also trying to titillate us with sex with 16 year olds anyway.
