You signed up for Amazon Prime for the two-day shipping, but you're staying for, well, partly for the two-day shipping, but also for the growing library of streaming content. Amazon Prime's streaming platform is best known for its original series like Man in the High Castle and Transparent, but the back catalog of movies is impressive—and, if you know where to look, very sexy. Like Netflix, Hulu, and most of the rest of the streaming world, Prime Video features a rotating selection of new (okay, new-ish) and classic movies. Yes, there's a lot of direct-to-streaming filler in the catalog, but, if you're willing to look, there are also some genuinely good movies. And if you're not willing to look? Well, that's fine too because we are and we've done the Prime Video selection deep dive so you don't have to. Amazon Prime's selection has a little of everything, but one category of movies that you won't find a curated list of on your home page? Hot movies for when you're in the mood. Nestled in among the hundreds of titles are some NSFW movies for when you're in the mood for something sexy. Here are some of the sexiest movies streaming on Amazon Prime.
