Interracial relationships

My boyfriend is from Greece and I’m African we are both 17 but he watches non stop white porn and we haven’t had sex yet and I get a lot of attention from black guys but only because of my body and me being as society would say it “thick” but he doesn’t pay attention and all his ex was from Greece and she was average brown hair olive skin skinny type of girl and I want to get physical with him but I can’t because I’m scared to talk about it with him and the fact that he watches that type of porn makes me feel insecure and that he doesn’t like my body and idk I’m just so confused
