I am pretty sure that story was just nasty gossip about her, no doubt started by one of the many repressive types (in almost all times from human history) who are frightened by the kind of unrestrained passion for sexuality a woman without fear can enjoy. They didn't have twitter back then, but they were still very good at 'talking shit' about others
The real story of her ongoing stable of strapping male human lovers (thoroughly tested first by her assistant female servants) is fascinating enough. You might also enjoy the no doubt more authentic story of Theodora, future consort of Justinian the Great, who as a young prostitute in Constantinople had a flock of trained geese who would nibble the grain from all over her body for the amusement of her fans. The Romans also staged beastiality shows in the Coliseum sometimes, the animals being trained beforehand with the aid of prostitutes. Unfortunately this was not always a pleasant experience for the women in the show, some of whom were being punished for whatever reason, and not all of whom survived.
