It is an infantile superstition of the human spirit that virginity would be thought a virtue and not the barrier that separates ignorance from knowledge.
Several hard-core Star Wars fans who had tickets for the first showing actually said that when the movie finally began, they started crying. Mainly because they realized that it's 22 years later, and they still haven't lost their virginity.
Virginity is such a personal thing. You can't judge anyone on it. A lot of young women feel they want to save themselves for the man who they think they'll love forever.
