The Innocent (1976)

During a scene in the men's locker room, a man is seen naked showering. Nudity includes full frontal.

Two scenes feature female frontal nudity--both also with a man--though in one the man is naked, the other he is clothed. In the first, the couple is fully naked, sweating and obviously caressing each other--it lasts about 1-2 minutes. The second the man pulls a nightgown off the woman and feels her breasts. About the same length as the other scene. Explicit nudity includes male and female pubic hair, female full frontal, and male full frontal save for his genitals due to position.
