You obviously can choose your own sources to base your opinion on what cuckolding actually is, but cuckolding is totally separate from interracial sexual relationships. The root definitions aren't close to similar ... cuckolding about a married woman cheating on her husband, the interracial sexual relationships about black & white. On this site and many others where the two come together, its usually the while, married males who have this "black cuckolding" fantasy or desire. I think for the most part, black males and white women, its not about cuckolding across racial lines, but experiencing interracial sex.
Got to remember, when white men develop the fantasy or desire to see their spouses have sex with black men, its to create the additional burn on emotions or emotional "high" ... its more taboo than just vanilla type "cheating". And if the interracial "high" isn't obtained by just sex, then they like to toss in pregnancy, owning, tiny penis syndrome, gangbangs, humiliation, etc etc. The white men who are wanting all this are wanting the added HIGH they get from this humiliation and embarrassment act. Of course, if the wife & black males go along with his desires, its just more fun for them as well. The problems begin when one of the parties decides they've had enough or want a change where the other two parties won't change.
There's really two types of cuckolding ... REAL & FANTASY Play ... ones intentionally caused, the other a total embarrassment to the cuck when he's aware of his wife cheating with other men. What we read a lot about HERE is the FANTASY Play or intentional cuckolding, I can assure you, when a woman is CAUGHT actually cheating on her husband, the reception she gets from her husband isn't anything like it is HERE. In fact, if they don't split up the marriage, at least they consider marriage counseling.
