I'm my boyfriends first girlfriend... Help?

So I'm my boyfriends first girlfriend/real relationship. We've been dating for a while, but since I'm his first girlfriend he doesn't really "know what to do" . I want to tell him what makes a good boyfriend and stuff like that. But how should I like bring that up to him when we are together? How should I ask if I can tell him what makes a good boyfriend so he'll know what to do in a relationship.
