ELI5:Do black men actually have bigger penises? And if so, do black women have deeper, wider vaginas?

From metapedia:

A 2007 peer-reviewed study appearing in the Tropical Journal of Medical Research has noted that contrary to "the popular belief that the black people generally have longer penile sizes" that in reality "there is no convincing scientific background to support the ascription of bigger penile dimensions to people of the Black race". In fact the study discovered that "the average erect length of the American Caucasians was surprisingly longer" than Negroidssampled, but that the latter were longer flaccid.
