I was in my older sister's bedroom. I was 14 and she was 3 years older than me. I'm not quite sure how to say that because she is still 3 years older than me, LOL! I had a friend who had an older sister that was one year older than him and he asked her if he could see her naked. She went along with it provided she could see him naked too.
Nudity is a state of being in which a human is not wearing clothing or specifically is not covering the genitals. Nakedness , or the loss of body fur, was one of the physical characteristics that marked the evolution of anatomically modern humans from their hominini ancestors. For many thousands of years, humans wore no clothing, which continues to be the norm in some isolated indigenous societies in tropical climates. It is generally accepted that the widespread adoption of clothing occurred as people migrated to other climates which required protection from the elements. In addition, as societies developed from being hunter-gatherers to being agrarian, clothing became part of cultural evolution as individuals and groups became differentiated by status and class.
