There are many sex scenes that are so explicit.

Two men and two women play games where they would strip. From there, they have sex very explicitly. Breasts and bare butts shown.

A woman goes into a clothes shop. A man from behind touches her. They take each others' clothes off. They have sex with breasts showing. Kissing, moaning, breathing, and penetrating.

Not all frightening. Apart from the prolong explicit sex scenes.
