In traditional cultures, it was assumed safely that the girl was a virgin. A man wouldn't need to feel insecure about it.
If you are a man who really cares about it, then don't marry an american woman. Go to asia and marry a young woman, by first meeting her family and sizing her up that way.
If you can handle that your wife has possibly been with someone else, then just put it out of your mind.
Neither men nor women have a right to know about such things.
