The only account for it we have is through our own eyes. There's no reliable data talking about the racial background of white women's sexual partners. Any study claiming to do so just can't possibly account for things like women being dishonest.
Women also have good intuition about this kind of thing too. They're experts at navigating social situations that they feel could hurt their reputation or status in the hierarchy. If a man randomly asks a a woman, "have you ever been with anyone non-white" she'll immediately know to lie because of the nature and framing of the question.
