I wish there was a study on the amount of black women that had interracial sex. That being said, it wouldn't be accurate because women are liars when it comes to their puzzy.
I bet you if you asked any of those black women that, that white boy in SC ran through if they ever sex with a white, most of them would say no. Black women have one night stands with whites on the low and then get ghosted but they block it out of their minds and say it didn't count. That white comedian Gary Owen's talked about losing his virginity to a black woman that he met at a club and they went to the hotel that night.
I personally believe more black women on average have had sex outside of their race than black men. We also tend to focus on white men which is a mistake because other races of men run through black women too. You probably wouldn't find too many black men that have had sex with Arab or Indian women but black women

.
Before black women sleeping around with whites was known as bedwenching, I noticed this phenomenon when I got to college as a young man. I personally saw black girls leaving parties with white boys every weekend.
To answer your question though, I can't say no, because i likely already have. I have never had interracial sex myself and i have no interest in doing so.
