I don’t know but I wanted to guess.
I doubt there is a universal answer but for some men maybe it is a validation thing. “My woman” is attractive to other men!
I’ve heard this explanation before, but I think it’s different for some guys who actually get off on being humiliated. I don’t know, I don’t get any of it.
No one’s mentioned the scientific theories, so here goes:
I remember reading a study that found that watching other men have sex (can’t remember with whom) improved a man’s sperm quality. Perhaps having competition encourages some people. Also, there’s a theory that human penises are shaped as “semen scoops” (search for “semen displacement theory” - there are papers on it) which, if accurate, also shows that our bodies, if not our minds, are ready for such competition.
I don’t know about humans, but there’s similar evidence in the animal kingdom. Not visual but - the Bruce effect, where an animal will miscarry if a pheromone produced by another viable male other than the one who impregnated is sensed. So she’ll be ready sooner. This is in estrous animals like rodents. I’ve never heard of that penis one, although some animals take it to an extreme - some animals, wasps IIRC, actually break off their penis and it becomes a plug, blocking further access.
I can’t really say that the feeling I get is “success”. As I said, it is only sexually stimulating. Maybe in deep down my brain, subconsciously I feel somehow sexually successful. And as a result of that, I have this fantasy.
Well I have a weird usage of this language. I am sorry for confusion. What I meant was that I hired a female prostitute. And the black guy was one of my acquaintances.
Yes, exactly. I just tried to figure out how it could feel.

Does a double-take
Obvious troll is obvious. Nothin’ more to see here, folks.
So…yeah, that sounds more like a voyeur thing, not cuckolding at all. You had no relationship with the woman, she wasn’t your wife or your mate, you just wanted to watch people have sex. That’s pretty darn common and even, dare I say it, “vanilla” as kink goes. I’m sorry to have to tell you this but…you’re normal. 
Why are you so disrespectful?
I’ve always thought cuckold fantasies have a “vicarious living” element, especially since many guys involved are bisexual.
I think there’s an element there of living out a fantasy of having the perceived sexual power of a woman – I think a lot of guys fantasize about being able to casually pick-and-choose partners and cuckold fantasies often involve a major element of that. Despite the fantasy of the man being totally powerless, it seems to me that the reality is that the “cuckold” is frequently the one arranging the meetings.
I’m going to analyze your post.
First of all, your screen name is Fear of the Dark and you claim to have a cuckold fantasy that involves a black man. Wut?
If it’s so common, why have I never heard of this?
Emphasis mine. It should be “every man has a thing.” It should be “wouldn’t it be great if you could somehow merge the two?” It should be “I think this why I have a cuckold fantasy.”
Your English must not be very fluent.
Emphasis mine. It should be “is this a healthy fantasy for me to have psychologically?”
Your post reads like a Nigerian scam.
I’m not saying this guy is legit, but apparently every other poster in this thread has heard of cuckolding fantasies. So maybe that part is just you. As to his language usage, did you ever consider that English may not be his native tongue?
Yes, YES! Now, humblebumble, punch him in the dick and go fuck his girlfriend.
THAT’S how you make a cuck!

Don’t do this again.

When I was a young teen, I thought it was sort of a cool idea, too. It was like I had this woman that I could hand out or not. I’d make all my friends jealous, but she was with me either way. Looking back on it, I realize that it was just part of not really understanding what a relationship was or what love was. It was from a time when sex was the goal of the teen relationship, and nothing more.
So I think when the day comes that you have a woman that you truly love and you truly want to keep forever and ever, you won’t think sharing her is a good idea. In other words, you’ll grow out of it.
Because you’re sheltered?
Don’t take this the wrong way, but you know nothing about me. And no, I don’t have fantasies about my girlfriend having sex with other dudes. She satisfies me just fine.
What is the deal with the interracial thing? I don’t think I’ve ever seen a cuckolded thing that did not involve a black guy as the third partner, and even in this thread it quickly came up in the first few posts.
Is there a black guy out that wants to watch his wife have sex with a white guy?
NM
I apologize.
At least, you didn’t ask, “didn’t you get that memo?” (Office Space reference). 
I’ll let myself out…
I think there’s more than one “deal” going on.
The simplest is the “black guys are hung” (or just assumed to be good in bed) angle, which…is only a little sketchy.
There’s also a safety element; I’ve seen couples suggest they only want black thirds because the wife wouldn’t “date” a black guy, just bang one. Substantially more sketchy.
There’s also a taboo element, since interracial affairs are still seen by many people as being “bad.” Incidentally, it seems like cuckold fetishes are common in the South or other rural areas. Medium sketchy?
And there’s also just people who find black men attractive and are indulging a fantasy so…why not?
The racial overtones of the whole thing have always seemed a little off-putting, but it does seem like the whole subculture is built around willing partners on all ends, so it’s hard to be too alarmed.
As to your second question…probably? Can’t say I’ve seen it, but, if my general interest in sexuality has informed me of anything, it’s that somebody is into everything.
Um, nothing except you hadn’t ever heard of a cuckold fantasy before this thread.
