Can someone explain cucking to me?

How is this a real fetish? How broken does one have to be to want others to fuck their wife. Does it come from a place of self hate? I don't understand.

Why is cuckold a fetish? I cannot think of anything worse.

The blind worship of Big Brains and Big Penises reveals more of your value system than you'll admit publicly: the quantity over quality approach that spawns slogans such as "Bigger is Better", the raw instinctual deference to Biggest Gorilla on The Block. The Primal Authority that your mind defends is the Big Violent Gorilla with Big Penis, who is superior specimen of your own kind.
You're judging character by the shallowest genetic fitness criteria that exists and the size of the stone age tribes..An evolutionary throwback to past of raw physical struggle and pre-technological power of the strong over the weak. By using size as the metric of reference, this confirms the pre-civilizational aspect of your mental frame: The Biggest Gorilla on the Block is the best of the tribe.
