What sort of communication do you two have? It sounds like you don't feel like you can be really open and honest with him about how you feel. Is this true? Are you afraid that if you are really upfront with him that you will scare him away?
Maybe the real issue here is not whether you are primary or secondary, but instead how open and honest you can be with each other.
So a way to bring it up might be:
"I've noticed that there are some things I'd like to talk you about, but I'm a feeling a bit unsure about how to go about it."
That gives him an opportunity to make a suggestion as to how to proceed, or he can ignore the invite which will also tell you something.
