Bestiality is everywhere in Greek mythology. It accounts for many a legend, including that of the Minotaur. Inflamed by passion for a white bull, Pasiphae made Daedalus construct a bronze cow.
Then she stripped naked, slipped into the bronze cow and pressed her genitals against the cow's vaginal opening. The white bull began lusting after the bronze cow and mounted her. From this strange union of the white bull and Pasiphae came the Minotaur.
The wife of the Athenian king had ritual sex, in a sacred stable, with a man representing Dionysus, the bull.
