Would you let a White Man fuck your girl?

To be brief, i have been thinking about it a lot recently, im not so much into the cuck shit and that but i saw my girl being maybe a bit too touchy, a bit too friendly with one of her coworkers, who happens to be this 6'3 nazi propaganda kinda beefy coworker of hers in a birthday party from a friend and i can't stop spinning it arround my head.

I hate to admit that i even find it arousing, its been like a week and half and i jerked off like 3 times to the idea.
It was outrageous, she was quite indecent in a almost public space in front of my and she obviously has a pussy fever with him and i'm unsure of how to confront it. Would it be wrong? At the same time i don't feel its wrong, it feels like almost eugenic, the cuck shit with all the black dudes is totally gross to me, i see them as a slave race, meanwhike this guy is clearly superior to me, im some mistery meat midget with a nasal voice and i am self aware. He reminds me of the jocks that poked fun of me at HS and it makes me feel inadequate
I dont know. Is it really wrong if it is clearly a racially superior man? Is it "nasty" if it feels even natural?
