Spies (1943)

A newspaper/magazine stand vendor is seen reading a magazine titled "sex."

Private Snafu, after getting himself drunk, ran up to a bar girl and implied prostitute and flirted with her and unknowingly strongly hinted at his being shipped off to Africa (said woman was shortly thereafter revealed to be a Nazi spy). Although the characters are still clothed in the next scene, it is strongly implied that Snafu had sex with the woman, with kiss marks being all over his face as well as the girl making physical moves. Recording devices are also shown on the woman's boobs.
