Are most American girls virgins?

There were six Vestal virgins. The high priest (Pontifex Maximus) chose by lot from a group of young girl candidates between their sixth and tenth year. They were required to have impeccable bodies and two living parents to serve in the order. This high priest pointed to his choice with the words, “I seize you, beloved.” They left the house of their father, were inducted by the Pontifex Maximus, and their hair was shorn. Now they were under the protection of the Goddess. Later, as it became more difficult to recruit Vestals, plebeian girls were admitted, then daughters of freedmen (Young, Worsfold, 21-3.).
