Revelations (1976)

Once upon a time, circa 1970, B.S. (Before Silicone), sex was actually free to be enjoyed without guilt, morality or fear of a life threatening illness. It was a time of bad haircuts, bell bottoms and blue eyeliner. It was also a time of sexual awakening. The film is shot documentary style, utilizing interviews with women expressing (and exploring) their sexuality via their work in hardcore films.
