This virginity concept has become quite obsolate these days. Anyways, anatomical explanation for virginity is absence of the thin membrane called hymen in the vagina.
This membrane is prone to rupture due to various reason like: cycling, brisk athletic games, insertion of finger etc and its absence should not be construed as something immoral.
Just as the girl has no way to know the sex habits of the boy, the boy should not jump to conclusion on the girl just because the covering sheath is not there.
It was one of the indicator on the character of the girl in ancient times when cycle and other brisk activities were unknown particularly to the girls.
