The NY Times posted a great article regarding children who love being naked and mixed reviews as to how long this is acceptable.
It's a great question. When do we start teaching people to be ashamed and embarrassed of their naked bodies?
For those of us who believe the body is free, natural, and ought to be experienced comfortably, we (particularly women) are generally assigned the label (and intended insult) of promiscuous. Funny how philosophical beliefs about the body tend to be demeaned and misunderstood as sexual statements (which also raises questions about the roots of sexual anxieties...).
Yes, the body is sexual, but one can express body, freedom, and self through more than simply sexual means.
