How do you tell a guy he is too touchy?

My boyfriend and I have only been going out for two weeks and he is way too touchy. I do not mean inappropriately, but always rubbing my arms, massages, petting my head (which bothers me the most,) and rubbing my leg. It is very uncomfortable to me and I have made up millions up excuses to get away from him touching me. Getting my soda, food, the remote, and thinking someone is in the driveway can only go so far. How do I tell him too stop without sounding rude or insulting?
