American Taboo (1983)

Full frontal male nudity but in a pretty obscured and dark shot, basically a silhouette from the side is seen. Full female nudity on a few occasions and sexual scenes. Close ups of her pubic hair as a man rubs it. The one female nude character is portrayed as a minor, but really the actress was 20 at the time of filming. There are also a few small pictures of fully nude women in the film.
