Appreciate the comments JP and DSOC.
In my admittedly limited experience Korean women are more likely to clean and explore the rear, lick and suck on the eggs, kiss, and in general be more user friendly with intimate things, than caucasian providers. My first experience at a Korean AMP was an eye-opener. I've done some reading and found it reviewed that Korean women in general, growing up, do not acknowledge or explore their sexuality (when horny they exercise, think of other things, pray, etc., rather than rub one out). Where does the good provider behavior come from? Maybe these attributes are a matter of training and $$ reinforcement? "If you want happy/repeat customers you need to learn to provide these things." I've tried asking about this and got (from provider) "sex is not important in relationship, family is" (children and husband are important and in her case working to provide money for parents). Having been reading reviews it seems that locally Chinese (tried two in San Fran last year and did not find them up to Korean experience) are not easily found, but accommodating Vietnamese are. Maybe I need to broaden my horizons.
