The Hemingway tale grew more interesting:
F Scott Fitzgerald’s wife Zelda was crazy and manipulative. In order to keep him from other women she told him that his penis was small and inadequate. F Scott sought Hemingway’s opinion. They went to a private location and F Scott Fitzgerald showed Ernest Hemingway his penis, and Ernest told him that it was fine. F Scott did not believe him, so Hemingway took him to the Louvre to show him the statues and paintings of similarly endowed men.
You just can’t make this stuff up!
