What does it mean to be 'shamelessly naked'?

My parents have had a kind of laissez-faire attitude to nudity at home. We live on an old farm, my parents actually rent out lots of our land to farmers and shepherds around us, in among a few small hills to the north west of Skofja Loka. From being a small child they have let me be naked if I wanted to be even if we had friends visiting. As a little girl I could hardly look offensive to anyone if I was naked, and playing, or sitting with other children who had been in our pool, when lunch was served to all.

I have even sat on neighbours laps naked! Shamelessly! I have sat shameless even as an older child, and a young adult!
