I'm Asian and a total newbie at this.  I've never been with a Caucasian lady and I also have the BIG disadvantage of being only 5'.  Asian ladies are wonderful, but I like to broaden my horizon.  I often wonder how comfortable a Caucasian lady will be with me?  Can anyone here shed some light?

The will be just fine with you.  Start contacting some ladies and have some fun!

Your stature will be no problem in this sport.  If your money is good, if you're clean, and if you behave like a gentleman, the ladies will welcome you. Enjoy!

You should try contacting the provider or provider's agency before you pencil the provider in.  The provider may not see Asian men, if you know this up front then your can focus your final research on selecting providers who will see you.  Believe me, knowing the a provider will see you early on in the provider selection process saves you a lot of time and insure that you will have the experience that you envision once you hook up with the provider.

I cannot say anything for any other providers specificaly but I know that i personaly have found many an asian man very attractive it is mostly dependent apon if you are as others have pointed out polite and what have you. I do not know what part of country you are in but maybe posting on one of the regional boards for your area?
