Full frontal male nudity on screen for a few seconds.
Another scene shows a full dressed Lily James watching as a man undresses in front of her. The man is then shown totally nude. Lily appears to look at the man's penis which is also visible to viewers for a couple of seconds.
After a woman comes into a man's bedroom for another matter, he orders her to undress. She takes off her dress and lays face down on a table. He enters her from behind. He continues to thrust into her while they both moan. He has to stop after a few seconds due to his war injury. Nudity includes female full rear and bare breast nudity; no female genitalia at all.
In a room you see a nearly nude prostitute and her full frontal nudity Is semi blurred seen
Woman knocks on man's bedroom door. Fully clothed, he answers the door and behind him we can see slightly out of focus his mistress nearly naked wearing only a garter belt. Bare breasts are seen. It is obvious the knock interrupted some sort of sexual encounter.
There are several scenes of implied sexual encounters. One is just a post-coital scene. The other shows a couple kissing and laying on a bed; they are then shown laying naked together afterwards. One post-coital scene is interrupted suddenly by someone entering the bedroom and discovering their forbidden liaison.
