Here are my very non biased calculations:
If african or arab,four guys
If white euro chad,four or five guys
If indian,six guys
If russian,people will murder you.
If ugandan,why are you geh ?.
If white US soiboi 12 guy.
If asian(and not a mongolian BVLL),20 guy and might need some fresh water to drink while thrusting
But if you are albanian,you wont need need company,just pull out your large alpha albanian Kar,pull it around your hip and shove you 25 inch dick up your ass,because albanians are the real gigas of this world,WE WUZ KARA BOGAS!
