Does your partner know?!

So I have openly named everyone that I have been with (sexually) to my husband. (Before we even got married)my husband has not told me who he was with unless I ask him then he tells me with out an argument or hesitation. now granted I do agree that what happen has happen and you should leave it behind you. But on the other hand I do feel like the person you are married to should have a right to know who and how many people you have been with. Just for the simple fact of A: you don't want them to be blind sided if anyone ever brings it up to them and then be caught off guard, I mean you are suppose to be able to tell your spouse anything! Right.. And B: for the simple fact of respect. I feel you should at least know how many people the person you're with (married or not) has been with. Does anyone agree?
