inter-racial relationships are almost always a white woman and a black man.
No.
Look about halfway down the page at a graph showing gender choices in interracial marriages. A smaller fraction of black women intermarry than black men, but the ratio is 22.0 % to 8.9 %. Not "almost always". Additionally, the fraction of mate selection (white, histpanic, asian, other) among those who do intermarry is nearly identical between the genders.
