I have always thought about this a lot watching IR porn but never really understood to the extent until I got my wife into the idea of sex with exclusively black men !
Yoi can call it a stereotype but it’s a fact black men have bigger dick not all but a lot do, and the majority of ones that do are fucking white women in some capacity (they might be with a black or Latin women but usually will fuck a hot blonde any day of week like most men would ) but the ones with big ass cocks get a lot of white pussy .
The interesting part I think is the physical compatibility! Black women are generally thicker big asses hips thighs etc , Black men are generally bigger , stronger , fuck harder n assertive and have bigger dicks . This makes sense as black womens bodies seem to be built generally to handle bigger stronger harder fucking black men . White women were built in general to take European white men which compared to their black counterparts are smaller less muscular and not as sexually agressive.
So when a black man and white woman start to have sexual relations it is the white womans body that adjusts to the black man! Of course physically the white womans ass and vagina are smaller and must adapt to the bigger black male cock entering her body and her ass starts to get a little bigger , my theory of this is because their body’s evolve from the physical sex and naturally your body will conform to its environment to protect its self . Also mentally is what I have noticed with my wife already and she has yet to taste bbc , they only look at black men in a sexual way as they are seen now as completely alpha males to her n women want to breed with alpha males it’s nature ! Also they start to incorporate them selfs into black culture like dressing , talking different etc to attract black men !
