Christmas gift help please?

i need to buy my boyfriend a gift for Christmas. We are teenagers & have been dating for 3 months. The problem is his family is rich & he already has everything. I don’t want to buy him something that is cheap because his family will think I can’t afford a nice gift(which I can’t because my family makes alot less than his family) He won’t tell me what he wants, he says he doesn’t want anything. So what am I supposed to buy him? Please Help!
