Should I do something in return to my new boyfriend? What should I do?

I have been dating him for over 2 months. He makes me feel good because he is attentive and romantic. He always remembers what I like and what I don't like and buys the little things for me. So I alway receive little surprises. I feel I should do something for him too, but I can't think of anything. I admit that I am not that romantic. He likes me because I am attractive, kind and down to the earth. Is it ok that I don't do anything, maybe wait until I do have some idea, that might be only once for awhile? Any suggestion?
