I only date people of a particular ethnicity (same ethnicity I am).

Now I'm less fussy when it comes to just sex but anything that is actually dating that could have a future the guy must be this particular ethnicity. For me it's not a fetish it's about having the same culture to raise children in.

Now this is just me and I can't speak for your bf but only you can decide if you can live with those thoughts if you don't trust his answer.
