I am from India particularly from the south and here families are very orthodox. It is expected that a girl remains a virgin before accepting a man in marriage. But I have had friends who lost their virginity to their boyfriends before marriage and had terrible breakups as well. They did not marry the guy they lost their virginity to. But they did not tell their future husband that they are not virgin. They told that they had boyfriend before but they did not get physical. I think it is best to maintain this way since you wont be triggering the male ego either. Do not tell your future husband or boyfriend that you are not a virgin. It will save you some slack.
