As my Wife has been with numerous black men before we met and married, it wouldn't really be a big deal to her.
I find the thought of her enjoying sex with men of other races, especially black, to be very exotic and exciting.
However, as she has no desire to cuckold me at this time, it doesn't really matter what I think, but should ever the time come that she chooses to do so, I will be excited and happy for her regardless of what ethnicity the man or woman happens to be as long as she truly enjoys herself.
