How much sex is actually in Fifty Shades of Grey? A recent Washington Post article placed the actual runtime of "actual sex and sexual-related activity" at 14 minutes and 17 seconds out of the movie's 125-minute runtime.
Fun trivia fact. But it also led us to the question, "How does that fit in with the pantheon of sexy movies?" That is to say, of all the movies that are ostensibly sex-focused in the history of films (and sex), how many of them actually devote large portions of their runtime to NSFW moments?
