For Christians, there is no verse in the Bible that sets man may have an affair before marriage and women must be virgin..actually it could not be possible that all women may be virgin and men not, if so WHO WOULD MEN HAD SEX WITH???

So, in my humble opinion..if a man DEMANDS virginity from his fiancee it is because he is still virgin... nevertheless, i believe that considering WESTERN CULTURE and all pressure caused by media as u said, if your couple is not virgin should not be a reason to decline marriage.. if your couple is fully honest to tell you the true, and both agree your love is more important, then why not getting married... God is the only who can judge and punish, we as Christians are entitled to forgive and forget as himself did it with our sins....
