This Czech/German film from 1933 is considered to be the first theatrically released, non-pornographic film to depict a female orgasm from oral sex. One of the most remarkable things about this film is that it portrays female sexuality as a positive and healthy aspect of life, and does not slut-shame its female protagonist for having sexual desires. Which is rarely seen even in today’s cinema, and was nothing short of shocking in the 1930s. The film also featured a brief nude scene of its 19 year-old star, Hedy Lamarr.
