I think your bf was being a little clueless regarding your feelings, but I don't think you have anything to worry about. At least, he was willing to be honest with you, and he seems willing to talk things out. Did you tell him exactly what actions or situations made you uncomfortable? I think if you talk it out more, you can start setting some boundaries, and he'll know what lines not to cross in the future so you're both happy and on the same page.
