These are the movies that taught us everything we wanted to know about sex (but were afraid to ask).

Porky’s (1981)

Directed By: Bob Clark
Starring: Dan Monahan, Mark Herrier, Wyatt Knight

Pee Wee, Billy, Tommy, and Mickey are four painfully horny high school kids growing up in South Florida in the 1950's. Desperate to rid themselves of their cumbersome virginity, they head out to a sleazy bar near the swamps called Porky's, where local legend has it that the owner will fix you up with a prostitute for a reasonable fee.

American Pie (1999)

Directed By: Paul Weitz
Starring: Jason Biggs, Shannon Elizabeth, Alyson Hannigan

Jim is thoroughly obsessed with sex, a fact of which his parents become aware when they discover him performing the sin of Onan with a gym sock while watching scrambled pay-per-view porn. Jim's buddies Kevin, Finch, and Oz are no less anxious to relieve themselves of their virginity, so they all make a pledge: they will go to bed with a woman in the three weeks before senior prom or die trying.

Secretary (2002)

Directed By: Steven Shainberg
Starring: Maggie Gyllenhaal, James Spader, Jeremy Davies

Sadomasochism provides the backdrop for a very unusual employer/employee relationship in this very offbeat romantic drama from filmmaker Steven Shainberg. Lee Holloway is a shy young woman, who, after a brief spell in a mental institution, is hired as a secretary by E. Edward Grey, a grim and ruthlessly efficient attorney. While Grey often criticizes Lee, she seems to thrive on his abuse, but one day he crosses a line...

Everything You Always Wanted to Know About Sex, But Were Afraid to Ask (1972)

Directed By: Woody Allen
Starring: Woody Allen, John Carradine, Anthony Quayle

Woody Allen's in-name-only adaptation of the once notorious sexual reference guide by Dr. David Reuben contains seven episodes based on "helpful" questions answered in the book. The best rank with the funniest moments of Allen's career, especially Gene Wilder's touching romance with the sheep ("I think we can make this work, Daisy") and the final sequence inside the male body.

Friends With Benefits (2011)

Directed By: Will Gluck
Starring: Justin Timberlake, Mila Kunis, Patricia Clarkson

A New York headhunter enters into a no-strings-attached relationship with her latest client, but finds things getting unexpectedly complicated when emotions enter the picture. Snappy, clever, and refreshingly contemporary.

Fast Times at Ridgemont High (1982)

Directed By: Amy Heckerling
Starring: Sean Penn, Jennifer Jason Leigh, Judge Reinhold

Many teen comedies of the 1980s and 1990s tried to imitate the verve and nerve of Fast Times at Ridgemont High, but few succeeded. A gabfest about sex, school, and status, it' a film that is emblematic of an era.

Road Trip (2000)

Directed By: Todd Phillips
Starring: Breckin Meyer, Seann William Scott, Amy Smart

In this raunchy comedy, Josh, a student at a college in Ithaca, NY, videotapes his one-night stand with beautiful sorority girl Beth.

Josh and his friends Barry, Kyle, E.L., and Rubin borrow a car and hit the road in a desperate bid to intercept the tape before Tiffany loads it into her VCR.

The Girl Next Door (2004)

In a stunning turn of events, Ian manages to chat up a beautiful blonde named Ms. Tasty, who's eager to be his first. The only thing preventing them from consummating their relationship now is the distance between them; Ian lives in Chicago and Ms. Tasty lives 500 miles away in Knoxville.
