You are asking for personal experiences so the information you get is always going to be scued. There is no conclusive evidence to prove or disprove any of the racial genitalia stereotypes. There are not a lot of scientists who can spend time and money on penis size. Not a lot of willing test subjects either. If you can get 385 people (the minimum if you want a confidence level of 95% and a standard of deviation of .5 for even a low standard for authenticity; you can look up "determining sample size" if you are confused on what this means ) of each race and all of the same general age then I take this whole post back. Even if such a study were to be conducted the results would be scued by factors such as living conditions, medical history and conditions, diet, background, and which part of Europe or Asia or whatever they came from. Asian men might not have smaller penises, maybe they do. Either way it would be stupidly complicated to provide a concrete answer.
