Sex. People have it! Yet for some reason, Hollywood still has a "protect our innocent eyeballs" attitude when it comes to graphic intimacy in movies – hence the existence of the NC-17 rating in the States. It basically the same as our 18 rating.

Over the pond, when the sex is too hot to handle, that's when not even an R ("Under 17 requires accompanying parent or adult guardian") rating will suffice. Here are some notable NC-17 movies:

1. The Dreamers

This 2003 romantic drama put Eva Green on the map, and featured lots of sex– some of it sexy, and some of it downright weird considering the film is about a brother and sister's intimate relationship with their mutual friend.

Either way, sex earned it an NC-17 rating – which is normally considered a death sentence at the office, but made this particular film all the more tempting.

2. Eyes Wide Shut

This movie ended up being released with an R rating, but only after being edited down. Meaning that yep, it was originally slapped with NC-17 thanks to plentiful and graphic sex. FYI, the Blu-ray release of the film features the unedited original version, if you want to check it out.

3. Blue Valentine

Like Eyes Wide Shut, Blue Valentine was originally rated NC-17, but got its rating down to an R upon appeal. The scene in question involves Ryan Gosling's character giving Michelle Williams' character oral sex, and he was less than thrilled about the rating.

"There's plenty of oral sex scenes in a lot of movies, where it's a man receiving it from a woman – and they're R-rated. Ours is reversed and somehow it's perceived as pornographic," he said in an interview.

"Black Swan has an oral scene between two women and that's an R rating, but ours is between a husband and his wife and that's NC-17?"

4. Showgirls

If you've somehow lived this long without seeing the infamous pool sex scene in Showgirls, you should probably stop everything and catch up on this monumentally iconic pop cultural moment.

That particular scene is just one of the many reasons Showgirls was given an NC-17 rating, and it's... a lot.

5. Lust, Caution

Ang Lee's erotic thriller is one of the top grossing NC-17 movies ever, and features explicit sex that Lee was hell bent on keeping in the film. "[In] America I think they are too loose on violence. I think that culturally they make an NC-17 rating equivalent to a porno movie and bad taste. I think that needs to be worked on," Lee explained.

6. Henry & June

Henry & June tells the famous story of Anaïs Nin's relationship with Henry Miller and his wife June – both of whom she explored sexual and romantic relationships with. To quote the film's LOL-worthy and very '90s trailer: "They lived an adventure more erotic than any fantasy." Interestingly, the movie almost got slapped with a X rating, but was deemed NC-17 to subvert the association with pornography that X-rated films typically have.

7. Shame

The reason for Shame's NC-17 rating should be pretty obvious: it's about a man (played by Michael Fassbender) who has a sex/masturbation addiction. As you might expect, the movie features explicit scenes of intimacy, as well as Fassbender completely naked.

8. In the Realm of the Senses

In the Realm of the Senses tells the story of Japanese Geisha Sada Abe, who's said to have killed her lover, and then cut off his penis and testicles, and carried them around with her in her kimono. ?. The film features unsimulated sex (meaning, the actors actually did it), and was originally banned in the United States.

9. Blue Is the Warmest Color

This film is a coming of age story that chronicles a lesbian relationship, and features graphic sex scenes that earned it an NC-17 rating—despite the fact that they used molds of genitalia instead of the real thing.

"We had fake pussies on," actress Léa Seydoux said of filming the scenes. "You have something to protect and tape it under. I don't make love on screen. We can fake these things, you can't fake feelings, but you can fake body language."

10. Y Tu Mamá También

Y Tu Mamá También helped make Diego Luna and Gael García Bernal Hollywood celebrities – and it's best known for its steamy love scenes – including a threesome with Luna, Bernal, and the woman they're traveling with. The movie was originally rated NC-17, but was released without a rating at all.
