It depends what is a virgin in your definition.Is it an intact hymen or having had intercourse with a man? There are many ways for a girl to have a perforated hymen and never having been with a man. Please talk to your clergyman or your doctor (gynecologist) about this issue if this bother you.
Ok than you so much
One more question.. A girl who finger herself.. Is she vergin or not?
There is nothing abnormal in what you are doing. If it bothers you spiritually, stop, but there is nothing in any religion that says that it is wrong for a woman to pleasure herself (as far as I know). There are certainly no medical adverse outcomes.
