Among my mother's pictures are several that show me nude as a child in our backyard, in the sprinkler, in a galvanized wash tub, running, etc, so I got an early start on the joys of no clothing. As I grew in a small farming community my cousins and I often played nude in the woods and swam nude together in the local river. It seems like boys and girls both started wearing swim suits about he age of 12-14 but all that early nudity stuck with me and I have taken advantage of every opportunity since to go clothes free.
I think the greatest advantage of growing up this way was learning early that boys and girls look different without clothes and accepting that as a natural thing rather than something to be amazed at. It didn't matter back then and still doesn't today. I just enjoy being nude and don't care if I am seen by men, women, children or whether those seeing me are clothed or nude.
