If reports are true, Carole Lombard didn't lose her virginity until she was 20, apparently to Howard Hughes (https://carole-and-co.livejournal.com/11206.html). But though she was relatively late to the bedroom, Carole came to enjoy her sexuality, having an array of partners in ensuing years. (And I'm guessing those partners all were male, that Lombard was a member of "team penis," as the Christy Plunkett character played by Anna Faris once described herself on my favorite sitcom, "Mom.")
So in addition to William Powell and Clark Gable, who might have shared her bed? Russ Columbo, probably; Robert Riskin, too. Same thing with Gary Cooper. But according to Lombard biographer Larry Swindell in "Screwball," Carole told her female friends that in a purely sexual sense, her best lover was, of all people...
...George Raft. (He's shown with Carole in a publicity still from "Bolero," which we know because it's marked on the back of the photo. They also co-starred in "Rumba.")
Did George and Carole go horizontal after posing for this pic? Your guess is as good as mine.
Raft tends to be remembered for the gangster roles he played, his shady real-life pals, his skills as a dancer and for the film roles he either turned down or was passed for. But George was a surprisingly successful lover whose Golden Age conquests included not only Lombard but Norma Shearer, Marlene Dietrich, Betty Grable and lifelong pal Mae West.
