At any given time, any one of us may be fully clothed, partially clothed, or totally naked. Why should we be ashamed of our bare bodies? There doesn't have to necessarily be a sexual connotation, although even if sexual stimulation did occur, it doesn't have to dictate any particular response. We cannot control how others dress. We can only control how we respond to it. You'll never be able to control nature by dictating dress codes. The only aspect of nature we are responsible for controlling is our own.
