Okay Willsrvu, let me get this straight you walk up to any black guy you see and ask can you serve them, or ask them if they will fuck your wife? If the answer is to either of my question is no, then you have just proved my point and you are just replying to get brownie points.
Big difference between a gentleman approaching a lady, smiling and saying hello, my name is ... , giving her a compliment on her earrings, hair style or dress and attempting to strike up a conversation and a white guy walking up to a black dude and asking him if he wants to fuck the wife.
One is the completely socially acceptable way men and women have initiated social intercourse for eons and the other an out of the ordinary kinky fetish act.
However, just to disprove your "point", if my Wife found a particular black man attractive enough (I assume you would approach only women you found attractive) to want to fuck, I would gladly go over to him, tell him that my Wife finds him attractive and invite him to join us.
As yet that hasn't happened, although she has found various men and women attractive as BDSM play partners and I have invited them to play with us for her or she for my benefit.
I skipped over my asking to serve a black man only because I am not free to do so. However, if I were, it would be no different than when I was approaching Female Dominants and asking if they would consider permitting me to serve them. Some accepted my offer, others blew me off. Guess what? One of them not only accepted my service, but eventually married me! Wonder if that would have happened if I gave up asking?
After surviving the first time, when I was a kid, I've never again been afraid to ask a girl or woman to dance or join me for a *******. I learned very quickly that the word no doesn't bring the world to an end.
Yes, on the other hand, stops it.
