He Wants Me to Be Black??! EDIT

So my boyfriend and I were talking about different things that turn us on and he told me he has a fetish for black women. That's fine except I'm white, I'm Irish so super pale with red hair. Then he said to me in all seriousness that he wants me to tan "as dark as I can" and wear a wig when we have sex!!

I'm not comfortable with any of this and this guy who I though was normal now wants me to be a completely different race! What do I do.

Not that I have anything against black women just I'm clearly not one and never can be and essentially he wants me to do blackface and fulfill some weird fetish and it grosses me out.

Edit:

Okay so I've read the comments and I just want to be clear that we are BOTH white, I'm Irish idk what he is but he isn't of color.

I talked to him more about it and he had zero shame explaining to me that he prefers black women but "can't ever find one". We live in a small town that's not multicultural at all. So basically he was dating me because I was all he could find. HE EVEN SAID GE WAS ATTRACTED TO ME BECAUSE I "HAVE CURVES LIKE A BLACK CHICK"!!! That's a direct quote!

I left his house and cried and then called him and dumped him. I don't even think he cared but I'm sitting here with my faith in humanity shattered.
