Should I Give Up On This Relationship?

My college boyfriend and I have been together for 5 months. He has a severe case of OCD, but he is a lot better now as opposed to being home schooled for 3 years and isolated from a lot of social interaction because of it. He keeps asking that I teach him conventional social mannerisms. We've been arguing a lot lately because he feels the need to have a logical, complex answer for every question he asks me when I like to give clean cut, simple explanations. He continually blames his OCD for his need to understand me. For example, I got an extra ear lobe piercing and he asked me why I got it. I told him because I wanted to. He doesn't understand its purpose and is uncomfortable with it because it's "such a permanent change to your body. It's going to take some time for me getting used to. I don't understand it therefore I am uncomfortable with it." Point is, I am getting tired of having to constantly explain myself. Should I give him a chance and hold on to this relationship?
