What part of Asia? Japanese are far less prudish when compared to USA or UK et al

I've been to Turkish baths and Koren baths before and only in the latter I was told to throw away the tiny towel I was holding to cover Mr Johnson. I don't know why in some cultures it is ok but in some others nudity ignites feeling of shame but after I threw the tiny towel I felt better. I guess peer pressure works both ways.

Sorry I meant South Asia.

But most people in the US are (very recent) descendants of Europeans, not descendants of Asians. Perhaps that's why the difference is interesting.
