Family vs. bf

So I’ve grown up in a very strict and racist white family. I have been preached on how “being with a colored male is wrong” but I’ve always been more attracted to them. I now have a “colored” bf for 3 years now. He’s started to wonder why I haven’t let him meet my parents or let him be around. I’m 15, so I’m still under a guardians care/ rules. But I really want this relationship to work out because of how much effort we’ve put into it. I love him, and my parents would never allow it. How do I tell them? And how do I handle it?
