Any correlation to nudity and ethnic background...just my experiences?

Just curious if there was any correlation to modesty and ethnic background. I've compared this in recent mages. Now feel free to correct me if I'm wrong but these are based on my experiences. Americans (blacks & whites) cover and d to a perfection and constantly tucking away at the sheets. They are also very overly tedious around glutes and areas considered too close to private parts. Orientals d you really good the first time and focus on a thorough mage that includes the glutes without asking...full body means full body to them and they are all business. Colombians do not care about the sheets at all...its not a ual thing but it almost feels that way. The lady I went to leaves your backside completely undercovered and once or twice with the intesity of the mage I was left frontally nude for a more then a few moments. Her asisstant on my second go...yeah I went twice...even completely removed the sheets frontally to dry excessive oils from me. They never skipped a beat, never made it ual they just overall did not mind nudity and did not put so much emphasis on keeping me covered. What are your thoughts...about the whole modesty and ethnicity thing?
