Why people highly care about virginity of girls?

There are many reasons people are highly concern about the virginity of girls. For instance, parents would preferably like their daughters to have no sexual experience before marriage, which is an important and cultural factor in many societies. They think that girls who aren't virgins will be attracted to having sex with other people outside their marriage. Besides, some religions assert that sex before marriage is sinful. Lots of media also encourage this idea that virginity has a price and when it's lost it can never be regained. Although studies have determined that the intact hymen is not a reliable indicator of a girl's virginity, people believe that once it breaks it can never be repaired. In the United States alone, girls under the age of 17 experience unintended pregnancies more than nine times as frequently as boys. They also have higher rates of sexually transmitted infections than boys, and a greater risk for contracting HIV/AIDS. In some cultures, young virgins are considered to be more likely to get raped or be mistreated by their husband. Some parents even kill their daughters if they learn that they are no longer virgins. On the other hand, several other studies suggest that sexually active women have fewer mental health problems than those who remain abstinent. Cultural factors additionally influence girls' perspectives on virginity and sexual activity early in life.
