This is the reason why Korean and Japanese porn are incredibly popular—especially the latter.
Whereas black men also similarly think of fucking white girls for they are petite and on the sweeter side.
However, porn has long been doing that.
Every white man has probably fantasized or saw a porn of a white man fucking a black lady—black girls are often on the thicker side and have bigger tits and ass and usually more aggressive in bed.
Interracial porn has always been popular and consumed, in fact there is a joke there is equality in porn—for races have been fucking one another without regards to their color in porn content.
Hence, if you feel weird for having this kind of fetish, then you must be new to porn! It plays well to the delusions and thus helps more when you are trying to jerk off to imaginations.
Even in films and television, it is becoming more common to see people of different races come together.
