Anybody who keeps abreast of common knowledge already knows that a truism in life is that Oriental men have under-endowed undercarriages. It's genetic. Studies have shown.
Of course, I need to mention that through decades of life I have never met a man, myself included, who owned up to having his penis measured -- uh, for an academic study. I need to qualify my measurement story because there was a wonderful hour with chickas on the beach in Puerto Rico where the girls had a contest over who had the longest foot. One thing led to another and I WON.
