From Deuteronomy 22:

Suppose a man marries a young woman and later he decides he doesn't want her. So he makes up false charges against her, accusing her of not being a virgin when they got married. If this happens, the young woman's parents are to take the blood-stained wedding sheet that proves she was a virgin, and they are to show it in court to the town leaders. Her father will say to them, "I gave my daughter to this man in marriage, and now he doesn't want her. He has made false charges against her, saying that she was not a virgin when he married her. But here is the proof that my daughter was a virgin; look at the bloodstains on the wedding sheet!" Then the town leaders are to take the husband and beat him. They are also to fine him a hundred pieces of silver and give the money to the young woman's father, because the man has brought disgrace on an Israelite woman. Moreover, she will continue to be his wife, and he can never divorce her as long as he lives.

But if the charge is true and there is no proof that she was a virgin, then they are to take her out to the entrance of her father's house, where the men of her city are to stone her to death. She has done a shameful thing among our people by having intercourse before she was married, while she was still living in her father's house. In this way you will get rid of this evil.

In some parts of the world, they still look for a blood-stained sheet for proof that the bride was a virgin. For example, Tonga: http://www.dailylife.com.au/life-and-love/real-life/the-virgin-sheet-ceremony-20130624-2ort5.html

In fact, I knew one Tongan man who divorced his wife after the wedding, when she turned out not to have been a virgin.

In many parts of the world, a woman just isn't going to find a good husband if she isn't a virgin.

Among men who pay for sex, many willingly pay a large premium for a virgin.

And, some women have auctioned their virginity on the internet, for quite a LOT of money:

In the West, Feminism has been quite successful in conditioning people to believe that a woman's virginity is unimportant--in fact, an American woman who was still a virgin might be regarded as a freak. The multitude of women, when they reach the age where they would like to begin having coitus, simply seek a local thug to perform the initiation.

But, even in our society, where gynocentrism has decreed that a woman's virginity has no value, an unruptured hymen can still generate lots of cash in the sexual marketplace.

So, why don't more women try to reserve their maidenheads for the highest bidder, rather than just forcing themselves on the high school bully?
