Virgin women do not need to have an unbroken hymen. A hymen is a human tissue that partially blocks the opening of the vagina about two inches deep. When a man inserts his penis or other object(s) are inserted into the vagina, it can tear or break the hymen which may result in bleeding. This blood from the hymen is important in many cultures, as it is a sign that the woman is a virgin; even though it is not necessary for the hymen to be broken to signify a woman's lack of virginity. The hymen can also, however, be worn away naturally by riding a horse, playing sports, or other recreational activities; it can also heal over time just like torn human tissue can.
