Can you tell if a woman is a virgin?

You could ask: For many societies, the presence of a hymen with a small opening for menstrual blood is the marker for virginity. Bloody drainage with first sex is used as proof. However, some are born without a hymen or one with a thin shelf,neither of which will bleed after sex. In some areas of the world, a surgical procedure rebuilds them. It also does not consider other forms of sex.
