This is a medical term that refers to a hymen that is intact at the time of a physical examination. Women who have no history of sexual intercourse, whose hymens usually do not rupture, and whose hymens are intact at the time of the examination are called unmarried vulvae, which actually means vulvae that have not had sexual intercourse. It is not very scientific to diagnose whether or not a girl is a virgin based on this item alone, because some girls have already ruptured their hymens during puberty due to strenuous exercise. Women who have had a history of sexual intercourse and who have undergone hymen repair will also show an intact hymen and an unmarried vulva when examined. You cannot judge whether you are a virgin or not on the basis of this examination, which is only an observation from the appearance, a description of the appearance and structure of the vulva, not a basis for judging virginity.
