Should I Call the "Other Man" My Wife Cheated With?!?!

You can read in my other thread how both my wife and I had a bout with infidelity in: My Wife Has Feelings for Another Man and it is Eating Me Up!!! Well, she swears that she didn't have sex with the guy, but I know that she went to his hotel room. Furthermore, she has not been forthcoming with information throughout this whole ordeal so part of me feels like she is still omitting information. I am thinking about calling the "other man" to verify some information about the extent of the relationship and particularly this detail of whether or not they engaged in sex. However, I am not sure it is such a good idea. Should I just have the attitude that I will never know? Should I just assume the worst that she is lying and that she really did have sex with him but still work on the marriage? Or should I just call the guy and ask him in a relatively nonaggressive way? I don't know what to do. I just feel like if the wife and I are going to stay in this marriage then we both deserve 100% unfettered honesty about what happened before. Otherwise what confidence do I have there will be 100% honesty later on? Please advise...thanks...
