Sex in Sinema Site
My new favorite film site...Looks to be a link from Tim Dirks' The Greatest Films at filmsite.org ("The Best Films of All Time - A Cimnematic Primer"). Here's their description:
Sex in Cinema: The Greatest and Most Influential Erotic/Sexual Films and Scenes
This collection, excerpted from the Mini-History of Sex in the Cinema site, lists some of the most significant milestones, and most influential and memorable sexual/erotic scenes and films on the big screen through cinematic history. Most of these films, with portrayals of sex and/or nudity, were considered quite erotic, groundbreaking, unique and/or controversial at the time.
Best and Most Memorable Film Kisses of All Time in Cinematic History
This is another site from the same folks.
