generally if you are shorter and genetically smaller overall you probably have a higher chance having a shorter dick compared to someone 6 foot at over who has a large shoe size etc. Like Asian men statistically have a greater chance of having a smaller penis and they also are generally shorter in height sooo possibly. I think height has more of an impact than race though like Indians are supposed to have smaller dicks because they are usually shorter, me and two of my indian australian friends are all close to 6 feet tall and I'm 6.5 inches long and 5.7 girth whilst the other two are 6.8 and 6 inches respectively so yeah. One of my asian friends who's taller than me has a 6.5 incher as well so I think it's pretty clear which physical trait is more accurate in assuming dick size.
I don’t know about anyone else but I’m 6ft 1” and have small feet size 9 for my height but have very large hands and my penis is 9.5” long and 5.2” around when hard.
