"Averted in Iamblichus' Babyloniaca. One of the many characters is the Egyptian Princess Berenice, who's described (in a slightly negative light) as a promiscuous lesbian who manage to sleep with the beautiful Mesopotamia. In the end, however, it's revealed that not only was Berenice crowned queen of Egypt, but she probably took Mesopotamia as her bride."

Is one of the most difficult works of antiquity for me to find online. The name Berenice implies this is a Ptolemaic dynasty princess, but it is fiction.

Does this trope have an equivalent for gay men?

Umm, sorry I don't know were else to ask. Dos anyone have screen shots of KP "back ground lesbian" and "Leslie Bin"?

Still new at this, but wouldnt sailor moon count? If I remember when they brought it state-side they went as far as to change the gender of one of the same-sex couple.
