Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

Quoting from Oarkwe and Ebuh 2007
The mean full-stretch penile length of the Nigerian Blacks was 13.37cm and the mean flaccid length was 9.36cm. Similar studies reported full-stretch penile lengths of 12.50cm in Italians, 12.18cm in Greeks, 9.6cm in Koreans, 13cm in British Caucasians, and 12.45cm in the American Caucasians. The penile length for Nigerian Blacks was longer than those of the other races, but the differences were only statistically different in comparison with the Koreans.
