A lot of white guys come into this forum looking for white females who will cuckold them with black males. That's not the way it works. Women aren't out there looking for subservient, wimpy guys with whom they can have a "cheating relationship" with ... they're looking for confident, successful, and well built, alpha guys. If "bbc" is a preference, then they look for that as well, but ultimately, most women look for that man that can provide most or all of the fore-mentioned.
Think of alpha & beta males this way ... if they were selling off store shelves, alpha males would be expensive, and beta males would be "buy one, get one free".
