My first,
I was a mid-teen living in Brighton when they opened the Naturist beach, and as I lived as much as possible by the sea, I was fascinated by this idea. So for many moons I was a gawper who would sit somewere near by, without the confidence to join in, but mesmerised by the happiness and freedom I could see.
I cannot remember my actual first day down there, but I do remember a time when I began to try it, and really enjoyed the thrill of no clothes.
Before I moved a way from Brighton, I had some fantastic memories of warm evenings after work, popping down for a swim, with clothed and non clothed girlfriends, with others who also enjoyed that freedom. Magic times.
I envy you having discovered naturism in your teens.
I was nearly 60 before I realised why I didn't like clothes and that there is an alternative! 🙁
