Full-frontal nudity, steamy threesomes, boundary-pushing BDSM – these raunchy films pushed the envelope, ruffled feathers, and titillated audiences around the world.
Pornhub isn’t your only option for salacious cinematic entertainment. TIME has done the dirty (literally) work of digging up the most sexually provocative movies of the last few decades. A list like this is bound to stir up controversy. Is Fifty Shades of Grey actually erotic, or a bored housewife’s barely-bawdy fantasy? Where is the line between art and smut? Is a dairy product an acceptable substitute for lube?
The answer to the last one is “no”. The answer to the others… well… that’s up to you. Have a look at TIME‘s choices and let us know what you think in the comments. If you’re not too busy furiously updating your Netflix queue, that is.
