NOTE THE IS A GENERALISED stereotyped not intented to be
specifically aimmed at anyone So Please dont get Offended! ITS A
JOKE~!!!
ang mo girl = open minded, easy going, willing to explore in terms
of sexual relationships, they can last alot longer than most asians
on the bed hehehe... 
chinagirl = narrow minded, fussy, impatient and overly sensitive oh
plus they make a hell of a ruckus on bed, and normally expire in
about 30mins...
singaporegirls = mixed back, u have the ultra conservative and the
hormone raging body humping sex craving little princesses haha, its
either no way...or ALL THE WAY...but they too expire pretty fast.
need endurance training sessions before u can explore their fullest
potential 
My pick: Singapore Girl, nuthing beats local gals!
