I would agree that her past is her past. Do you still love her and would not knowing this information change things? When people are young they do things that they regret or wreckless etc. Do you want your wife to revert to her past and be wreckless and sleep around with multiple people? People change and 14 years is a long time. I would try to let go of her pastand embrace the present between you two. Those wild times were probable not very fulfilling to her, otherwise she would experess a desire to do that again right? I don't agree with her casually bringing it up, and I would find that aggrevating if my wife did that without me asking. I could see how you could be upset, but do you really want to be angry with her over something so long ago and before you were together? I would tell her things like that bother you and to not casually bring them up.
