skylar,
hmmm... lemme tink tink (see i so good to u, your "cock" qn i oso gif u scientific answer)
You r tokkin abt dick, not balls rite?
The 1st qn u haf to figure out is: Is he having an erection? Chances r he could feel u gazing at his dick n therefore got aroused... otherwise maybe u r wearing a bit body-hugging 2day n he got aroused looking at u... u noe travelling in the MRT on a bo-liao Fri morning, sometimes really can make people "xian lu fei fei"
So if he's having an erection, and his dick is piercing thru' his pants, either he's too powerful, or he's wearing crocodile brand underwear of the wrong size!
Its harder to answer if he's NOT having an erection. Generally for Asians, unerected penis is quite small like u normally see. Ang Mo's penis r significantly bigger even unerected, dat's a fact.
So if his dick is big even in flaccid state, this could be either genetics, or if not he could be taking "penis-enlargement pills" or he's undergone some surgery to increase his size.
Hope the above answers your qn. Any further queries can be clarified face to face when we meet next time.
