4. Superbad (2007)
So these two virgins walk into a bar house party. The fat one gets menstrual blood on his jeans, the one who looks like he doesn't have pubes just wants some intimacy. But somehow, like any good teen sex romp, they both get the good-good ("good-good" being the affirmation of their BFF-dom).
For a teen sex comedy, Superbad has remarkably little sex, but it does have McLovin and lots of illustrated penises. HOLLYWOOD MAGIC!
