Interesting point that shame is a product of the culture in which we are raised. That makes sense. And the shame we feel about our bodies has changed over the years, we used to be more conservative in the west,and covered up. It's all relative to time, place and circumstance. There seems to be no fixed norm or standard. Holy men in India walk around naked covered in ashes in some parts of the country. Probably because it's very hot, as well as being detached from mainstream culture or civilization.
