For me I think it's been a combination of factors that I can say had an influence, but I'm sure there are a number of ******* factors that will forever remain elusive and ineffable. I know reading erotic stories about black men taking white men's wives or black men impregnating white wives had an early influence and over time this interest in these stories impacted upon my sexuality. As time passed and my sexuality changed I wanted to be the white cuck whose wife loved big black men. At first I felt uncomfortable and almost ashamed at this change, but now I feel liberated and see the cuckold role as a natural one for me.
I could also see the physical attraction black men and white women had for each other and this only reinforced my developing cuckold feelings. Add to that the beauty of the white female, the masculinity of a big black male and how well they complement each other sexually, and you've got a full-blown interracial lover and interracial cuckold on your hands!
