@Pioneer1, I would be careful when trying to tie genetics to culture, particularly for African Americans. You can't look at a person and tell what their genotype is. Even if you had complete knowledge of one's genetic coding, science simply does not know enough say that these genes are associated with sexual prowess.
PLUS American Black and white share people share so many genes it is virtually impossible to use these to distinguish between them based upon genetically determined behavioral characteristics on a "racial" basis. Seriously, it is wrong to think of it this way.
Besides, many of the things were associate with culture have nothing to do with the color of one's skin. Culture is man made often arbitrary. I know many Black people, for example, who are culturally white (based upon they way they speak, their dress, the music they listen to, who they associate with, etc), and I've met white people who are culturally Black. This example is probably just a function of where and when these people were born.
I wish they would get rid of the word "race," because it confuses people about the nature of humanity, creating unnecessary barriers between us.
