Dubbed the "f*ck of the century" by Michael Douglas's character Detective Nick Curran, this classic erotic thriller isn't playing around when it comes to sexy movie scenes. "Basic Instinct" tells the story of crime novelist Catherine Tramell (Sharon Stone), who finds herself being the suspect in the murder of a rock performer. After being caught between a rock and a hard place after falling for Curran, their chemistry builds until it reaches an undeniably sexy (and thrilling) peak. It's one for the movie sex scene hall of fame, for sure.
