Starting to think I have issues with confrontation

My boss and I are leading a financial peace university class and it’s great. I can see how much he enjoys helping people with money by the enthusiasm he has with the stories he shares. We kind of have a good cop - bad cop thing going on. His delivery sounds more harsh while I try and guide people into opening up. I do need to find a way to get him to share less though. It’s not giving the class the space to share. I just don’t know how to bring it up.
