Lets suppose you are in class and you go to your tutor at the end of the day and you say that you are confused about a certain problem in class on that day. And all these problems were different. Then over the week you have had several confusions and the tutor would be right to say at the end of the week:

I can understand your confusions

Unless of course, she was confused about your confusions because you never explaimed things correctly. Then she would be right to say:

I'm confused about your confusions.

So you can see from this example it makes sense to say 'confusion' or 'confusions' depending upon context.
