Yes, according to some accounts, Zeus did sleep with Aphrodite.
While not a standard or primary pairing in Greek mythology, certain sources indicate an affair between Zeus and Aphrodite. This relationship resulted in the birth of Priapus, a god known for his large and permanent erection, who was described as ugly or deformed. The Suidas lexicon specifically mentions Aphrodite having an affair with Zeus, resulting in Priapus. Hera, Zeus's wife, is said to have cursed the child due to jealousy over the affair.
Therefore, while Aphrodite is more commonly associated with other lovers like Ares or Hephaestus, the affair with Zeus is present in some narratives.
