The primary difference between a virgin and a non-virgin girl is that a virgin has not engaged in sexual intercourse, while a non-virgin has.
In more detail:
- Virgin: A person who has not had sexual intercourse. This is the generally accepted definition.
- Non-Virgin: A person who has had sexual intercourse.
It is important to note that the term "virginity" is a social construct and the idea can carry different meanings for different individuals and cultures. The physical indicator often associated with virginity, the hymen, is not a reliable indicator as it can be broken through activities other than sexual intercourse (exercise, tampon use, etc.) or a person may be born without one.
