I Am Maria (1979)

A family of four showers while a prepubescent girl watches. In this scene you see a prepubescent girl's vulva and an adult male's phallus in a close up. A woman's breasts and pubic hair are seen as well. A small toddler-aged boy is present but reveals no nudity.

An adult male, his wife, and prepubescent daughter are sitting in a sauna with another prepubescent girl. The male's pubic hair and partial view of his phallus is seen. The woman's breasts are seen. The daughter's chests and partial vulva is seen. The other girl's breasts are shown.

Two prepubescent girls are in bed together naked. They tickle each other and play. One cups the other's breasts. They then snuggle. Sex is not implied or inferred.
