Endless Night (1972)

Pretty much from start to finish, this movie is about sexual learning, distortions, deviations with lots of full female nudity. Including a scene where the camera simply focuses on a woman's exposed vagina while the narrator describes the man's sexual dysfunction.

Due to the whole movie being filled with woman in their panties too much and them being naked, the movie was banned from television ever since the 70s.

From a distance, the subtle glimpse of Velly's vaginal lips are visible as she engages in sex in the barn.

A woman wearing a skirt without panties is standing, and we see a close-up view of her shaved vagina from bottom.

Several women are seen outdoors in the nude, with their breasts and buttocks exposed.

In this scene, a black and white woman engage in intercourse, both fully nude. Their breasts, buttocks, and hairy pubic areas are visible.
