"The Bible does not forbid premarital sex.
There is no passage of the Bible that references premarital sex as a sin against God. The association between sin and premarital sex is a new Christian idea. The only possible reference to premarital sex being a sin in the Bible is in the New Testament. This premise although, is generally dismissed by theologians because the Greek word pornei, or sexual immorality is commonly incorrectly translated into the English word fornication.
In Biblical times women were the owned property of a man. Men ruled over women and their children. Women had very few, if any, rights, and men often bought women from their families or at an auction, usually at age twelve and a half. The fathers owned the women (daughters, wives, concubines, handmaidens, servants etc.) and if you wanted to have intercourse with one of his properties, then you had to ask his permission.
If a father sold a daughter, he would get more money for her if she was a virgin. Non-virgins were less expensive to buy. If a man purchased a daughter at a virgin price, and she was not, or she did not bleed during intercourse, then he could return her to her father and get his money back.
Most marriages were arranged for financial reasons. Many couples never even met until the day of the marriage. On the day of marriage the proposed husband would give a dowry, or monetary compensation, to the father of a bride. The price of the dowry was different from woman to woman, was determined by the father, and was based on the woman's beauty, ability to bear children, strength, household skills, and status as a virgin.
In the Old Testament, many verses that people site for being against premarital sex are actual verses against stealing another man's property.
In Exodus 22:16 - 17, "If a man seduces a virgin who is not engaged, and lies with her, he must pay the bride-price for her, and she will be his wife. If her father absolutely refuses to give her to him, he shall pay money equal to the bride-price for virgins." According to this, the only reason any wrong was done is because the father of the woman lost money when the man and the woman consented to having premarital sex without her father's knowledge. This passage showed that through premarital sex, the man is actually stealing from the woman's father, the difference in value between her as a virgin and her as a nonvirgin. It does not show that premarital sex is wrong.
In Deuteronomy 22:28 - 29 it says, "If a man finds a girl who is a virgin, who is not engaged, and seizes her and lies with her and they are discovered, then the man who lay with her shall give to the girl's father fifty shekels of silver, and she shall become his wife because he has violated her; he cannot divorce her all his days." This shows that forced premarital sex, or rape is also stealing, but unlike the book of exodus, this trespass provides a punishment, as the male rapist not only stole from the woman herself but from the woman's father as well.
Another example of premarital sex in the Old Testament is given in Deuteronomy 21:10. This is a case in which a man takes a woman captive and then if he wants to make her his wife he must follow the conditions it sets forth, and then have intercourse with her. Then, if she is found to be desirable he has the option of marrying her or sending her away. This passage not only possibly condones premarital sex, but maybe even divorce as well.
Even the 10 Commandments don't forbid premarital sex. Most Christians would classify premarital sex under the seventh commandment, "Thou shall not commit adultery," but adultery is defined as: voluntary sexual intercourse between a married person and a person who is not their spouse. If neither persons are married, it cannot be adultery."
