As far as females wanting to sleep with other men I suspect it has some thing to do with genetic diversity. Especially wanting to sleep with black men.
The more diverse the genes the stronger the offspring.
The genetic trait which makes us attracted to women or men with different accents and different traits is what made our genes strong. Nothing can be more obviously diverse than someone with a different skin colour. I certainly don’t deny the attraction to alpha males but I think genetic diversity plays a part.
Another interesting fact is that from my perspective, is that my wife really wasn’t interested in infidelity until after we had our children. And at that point she became interested in men completely different from me.
Thats when she started to become fascinated with black cock .Now there’s no denying that when she got her first taste that her desire to be a queen of spades stemmed at least partially from physical satisfaction. Once her tight white pussy learned what orgasms while being filled with a thick black rod were like.... well there was no turning back. But I think the initial attraction was her Instinct to spread her genetics around and increase the likelihood of her survival through diversity.
Initially her mind was looking for pleasure but I think the main driver was her desire to breed.
Thus the craving to fuck black men bareback and be filled with their cum and her pregnancy fantasies
