The Maidens are three different goddesses, who are not allowed to be in an affair or relationship to any demi-god, mortal or immortal. They are also known as the three 'Virgin' Goddesses, and Athena, Artemis and Hestia. In their lives, Athena and Artemis have fallen in love. Athena with a demi-god named Heracles, and Artemis with a mortal prince named Actaeon. They have clearly broken the rules of Virginity, but they kept their love a secret.
Hestia has never fallen in love with someone, but maybe shared a strong relationship with Zeus, but never had any affairs. She works with the major gods and goddesses in Mount Olympus and would be too busy to find love and break her Virginity.
