After the first sex scene listed, Elizabeth gets out of the bed to change her nightgown, you see her nude from the back. You see her back, upper buttock, the side of her breast and nipple.
There is a consummation of Elizabeth and Neeley's marriage the first evening in the house. In that scene there is a few moments of thrusting, moaning and sighing from Neeley, but no visible nudity. The entire scene is shot from over Neeleys shoulder as we watch the pain on Elizabeth's face at Neeley's rough treatment.
There is also a later scene of rape that occurs between Neeley and Elizabeth that is quite frightening. No nudity is shown but there is a lot of thrusting and screaming throughout the scene.
