Average Manhood Sizes From Around the World Revealed: Africa Tops Chat

According to the data, British boys have an average erect penis length of 13.9 centimetres while the Australian average is 13.2 centimetres.
The study, by controversial scientist Richard Lynn, has collected data showing the average penis size of men from 113 countries which Lynn claims proves that racial stereotypes around penis size hold true.
While Koreans came bottom in the survey, measuring up at just 9.6 cm, the Republic of Congo came first with a healthy 18 centimetres.
Media reports show UK nationals are pleased to come in ahead of the French with 13.9 centimetres to their neighbours' 13.4.Lynn, British Professor of Psychology at the University of Ulster in Northern Ireland, has previously released research identifying intelligence differences between men and women as well as racial intelligence gaps.
His study says that the findings confirm previous theories of "race differences in penis length" with African 
men the best endowed and Asian men the least.
However, Lynn's evidence has been called into question, as the figures were taken from a non-academic website that collected data on penis length.
The findings were published in the journal Personality and Individual Difference.
