Recently I watched MR. SKEFFINGTON starring Bette Davis. The film was released by Warner Brothers in 1944, ten years after the production code had taken affect. This dialogue is in the film:
Fanny (Davis’ character): Jim, do you ever think about the old days here at Gramercy Park?
Jim Conderley (played by John Alexander): Now and then– in the shower.
Maybe this is the first and only time self-gratification is referenced in a classic Hollywood film of the 1940s…? Interesting that it slipped past the production code office.
