I am a white american guy
I had sex with
White (american, english, turkish, italian)
Chinese (both mainland and singaporean)
Black(american)
Japanese
I would say my favorite are the japanese
They always seems VERY active and enjoy it ALOT. They are very
flattering too and make a big issue of penis size. Its strange
because they have the tightest pussies, and usually cant accept the
entirety of my dick. But on a psychological level they seem to
really like big penises.
Black girls are good cuz they are very enthusiastic and demanding
in bed. They also make a big issue of big penises, which surprised
me cuz I used to think all black guys have giant ones. These girls
told me some do but most not bigger than 7 inches. On the downside
I think black women are not very attractive compared to other
races. I was happily surprised that theyre pussies arent at all
loose like some people try to say they are.
white girls that I had sex with tend to be either very cold fish,
or very violent.
The cold fish suck of course. And im not that happy with the
violent ones biting and scratching and asking me to slap them
around. not really my thing...
The ones with big breasts also tend to have looser pussies. Stick
with the tiny chested girls 
I had sex with chinese girls more than any other. They are a close
2nd to the japanese. There is an occasional cold fish that makes
the guy go slow and always complains of pain. But thats rare. Most
are very impressed with a big dick, but cant seem to handle it. One
VERY good thing about chinese girls is they are SO easy to give an
orgasm.
about 95% of the chinese girls ive been with came in the 1st 5 mins
of sex, and didnt stop cuming until I came. This is lots of fun for
any man I am sure.
Nothing more satisfying than making a girl feel so good she loses
control of herself and starts shouting and thrashing around

On the downside of chinese women, they tend not to be very
adventurous in the bedroom. Some are though.
Anyway, thats been my experience, what about the rest of
you?
