Ancient men's paranoia about chastity mainly came from the concept of private property. If the wife is not a virgin before marriage, it is difficult to ensure that the child comes from her husband's blood, and it is also difficult to ensure that her husband's property will not fall into the hands of "illegitimate children." At the same time, since the wife is the husband's private property, then the husband must ensure that he has the "first right to use". If he eats "leftovers" and uses "second-hand goods", it will greatly hurt the man's self-esteem.
Another reason for the virgins' love is that the ancient people in China were superstitious about "virginity", believing that making out with boys and girls can keep you healthy. The ancient sexology book "The Secret of the Jade Palace" in the Six Dynasties said: "Those who want to get big profits should be virgins." In the classic novel "The List of Gods", it is mentioned that the use of the "ten thousand plum blossom account" (the first time a virgin's intimate hymen is broken and her account is stained with blood) can greatly break the enemy of ghosts and gods, which also shows the precious magic of virgins.
