I had a similar experience in graduate school with an Indian colleague. I am American, but the Indian culture is just soooo different in sexual matters. He may well have a family (wife and children) in the old country that he does not feel a need to tell you about. I was horribly insulted by my paramour's attitude toward my freedom, but i understood it as my parents were Italian and had tried to raise me with the same taboos.

I would not give your friend a copy of The Little Prince. I dont see from your post that you love him so it seems confusing and inappropriate to me.
