Scripture ALMOST all of the time uses words to identify the GOOD from the TOTALLY EVIL. Young girls were protected because of morality but also protecting genealogy. Mary was with Elizabeth and not out running around so that Rubel Shelly could compare her to Cherokee Sal. Scripture uses Parthenos to tell you Mary was not knocked up before she was married.

Hom. Il. 2.511 And they that dwelt in Aspledon and Orchomenus of the Minyae were led by Ascalaphus and Ialmenus, sons of Ares, whom, in the palace of Actor, son of Azeus, Astyoche,
the honoured maiden, conceived of mighty Ares,
when she had entered into her upper chamber; 
for he lay with her in secret.
Pi.P.3.34, His mother, the daughter of Phlegyas with his fine horses,
before she could bring him to term with the help of Eleithuia who attends on childbirth,
was stricken by the golden  arrows of Artemis in her bedroom
and descended to the house of Hades, by the skills of Apollon.
The anger of the children of Zeus is not in vain. But she made light of Apollon, in the error of her mind, and consented to another marriage without her father's knowledge,
although she had before lain with Phoebus [Apollon] of the unshorn hair, 
and was bearing within her the pure seed of the god.
Apollo, Apollyon or Abaddon UNLEASHED the Locust or His Musical Worship Team. He is the father of musical melody, perverted worship and leader of the Muses. They are called sorcerers in Revelation 18 named after the original Babylon Mother of Harlots and they WILL BE CAST ALIVE INTO THE LAKE OF FIRE
She did not wait for the marriage-feast to come,
nor for the full-voiced cry of the hymenaeal chorus,
such things as unmarried girls her own age
love to murmur in evening songs to their companion.
Instead,  she was in love with what was distant; many others have felt that passion.
There is a worthless tribe among men which dishonors what is at home and looks far away, hunting down empty air with hopes that cannot be fulfilled. Such was the strong infatuation  that the spirit of lovely-robed Coronis had caught.

but she did not elude the watcher.
Even in Pytho where sheep are sacrificed, the king of the temple happened to perceive it, Loxias, persuading his thoughts with his unerring counsellor: his mind, which knows all things. He does not grasp falsehood, and he is deceived  by neither god nor man, neither in deeds nor in thoughts.
Knowing even then of her sleeping with Ischys, son of Elatus, and of her lawless deceit, he sent his sister, raging with irresistible force, to Lacereia, since the girl lived by the banks of Lake Boebias.  A contrary fortune turned her to evil and overcame her.
And many neighbors shared her fate and perished with her; fire leaps from a single spark on a mountain, and destroys a great forest. But when her kinsmen had placed the girl in the wooden walls of the pyre, and  the ravening flame of Hephaestus [Tubal Cain] ran around it, then Apollon spoke: “I can no longer endure in my soul to destroy my own child by a most pitiful death, together with his mother's grievous suffering.”
