That's pretty easy, just don't go too far sexually for now, and go on dates that allow you to talk. For example, you could take her out to dinner. That way you can talk the entire time and just ask questions about each other. Or since it's getting to be spring, you could go for a walk somewhere. There are lots of options, just try and stay away from seeing a movie because you can't talk during that.
Honesty, you could probably just be to the point and just tell her you think its best if you slowed down and got to know each other. I think she would understand, and probably would like getting the chance to learn more about you.
