There are a couple of instances of eyebrow-raising dialogue, and the women mostly have secretarial-type jobs, but it's par for what you'd normally expect to see in 1950's books (even science fiction the imaginations of mid-century SF authors had their limits), and nothing was too far out of line. Double Star, I think, does the job pretty well. My (self-imposed) mission was to find a Robert Heinlein story where the enjoyment of the tale isn't swamped by the offensive content for which Heinlein is, unfortunately, well known. But somehow one appearance as a double leads to another, and another. Larry's first task: fool the Martians during a vitally important Martian adoption ceremony. He promptly finds himself whisked off to the planet Mars, standing in for one of the most important political figures in the solar system, who has been kidnapped. In Double Star, a 1956 Robert Heinlein novella, Lawrence Smith (aka Lorenzo Smythe or "Lorenzo the Great"), an out-of-work actor, accepts a job to impersonate a man for a few days, without, perhaps, asking as many questions about the job as he should have.
