in some gay circles, it is said that you can tell a mans penis size by his hands and feet. If the fingers are long and the hand is larger and the foot size is large than the dude usually has a bigger size cock. However, heritige has something to do with this also, i.e , Latins, slovaks, russians, jews, are known larger size cocks.
German and irish are known for their thickness or width in gay circles
