You are young, I assume.
Let me explain something to you... if you feel he is moving too fast, you tell him... in your words. You tell him and don't worry about what he may think. If he can't respect what you have to say about this, then he is not the one you want to be with. If he is truly a good guy, and cares about you, he will understand when you tell him and he will deal with it.
If he doesn't deal with it... if he gets mad... if he says he's going to break up with you... then he is only using you and doesn't care as much as you think he does. You don't need that. You don't need someone like that. There will be plenty of other guys in your life. Plenty that will respect you and your wishes.
EDIT- Is this the same guy from your earlier post?

If so, then you are wasting your time with him. He sounds like a jerk.
