To understand black women you have to understand black sexuality on the whole.
Notice that
almost every successful black person (in the Western world) when interviewed or receiving an award will "Thank God" for their success. With that said, religion and sexuality often don't mix too well. Even Tyra Banxxx, one of the most enthusiastic black performers (in her teenybopper.com days) quotes her religion as "Christianity".
The nice-looking Black women who are interested in porn are out there tho.
