I don't have time (due to being in the middle of work) to write up my thoughts on the best way to handle this though I agree with cyber-sibe's suggestions, and I know there are others here who have a lot of experience in this area. I do want to say however, that like raising and dealing with issues with kids, you are going to get a lot of varying feedback on the best way to handle it. I think you should pick one method that you feel most comfortable with and stick with that very consistently. Do ask people not to try to pet him for now though, especially on the top of the head. I'm sure you'll get more in depth advice here too. My best wishes to you.
