There is no statistical difference in penis size between races. Black people having bigger dicks is a myth that comes from slavery. The idea comes from when white people colonized west Africa and they considered black men and women to be sub-human and animalistic, and they made up the idea that black people had large animal-like dicks and were dangerous rapists that could hurt their women. They used that to justify slavery back then but the myth still exists today.
