Race has nothing to do with size, I have seen big and small cocks in men of every race. Big size does not mean sexual skills or attitude which are important factors to most women. Finally, I have seen cucks with 8" & 9" cocks. If you want to be a cuck you will be no matter the size of your cock.
For me it goes like that (and that's only length, don't forget girth which most women prefer over length):
1-3: Tiny
3-5: Small
5-7: Average
7-10: Big
Over 10: Huge
That is true most white men are under 5 inches
my love you and my wife needs bllack cum inside your bellys
