So when the syrupy music kicks in - the guy kisses the chick
that means they banged? Or just soft petting -- 1941 style? I really don't know.
House: I have been on a date before.
Wilson: Not since disco died.
Of course that's what happens. How else were they going to let us know they had sex? The Production Code was still in effect, and films would not be released until they were given a certificate of approval. They went as far as they could in this film, the beach scene with Lancaster and Kerr was considered pretty racy, as everyone knows.
People had sex in real life and everything, same as now.
