American Pie (1999)

Jim is your average healthy re-blooded virgin -- he's desperate to "make it" with a woman. The stakes are raised when his parents catch him with his pants down watching porno films in his bedroom, his one experience with a beautiful exchange student turns into an online disaster and his friends make a pact that by the day of their high school graduation, none of them will be virgins. Pressure's on, but will Jim rise to the occasion?
