Open Question: Why in movies black men are always in intercial relationships?

like I don't even remember the last time a black guy was with a black women. How come they always make black men with other races, but make asians always be with asians, latina women only with black men, but latino men with latino women, black women always with black men, white men always with white women, and white women usually with black or white? i'm not being racist, why don't they pair up other races too? you don't see asian men with latinas, or white men with black women it's always black men in interrcail relationships.
