In what way does Calypso accuse the gods of a double standard?

In Book 5, Athena asks Zeus to intervene with the obstacles that are deterring Odysseus from getting home.   Zeus sends Hermes, the messenger of the gods to go to Calypso's island to tell her to let him return to Ithaca.  When Calypso hears of this, she rants on about the male gods, and how they interfere with the happenings of the female gods.  She doesn't understand why they are allowed to take human lovers, while the female goddesses are not.  However, Zeus wins in the end, and Calypso supplies a boat for him to leave the island.
