My parents were naturists so I was a naturist as a child. I grew up around nude people. Consequently I feel just as comfortable without as with clothes. Well no not quite, I prefer no clothes.
Wherever I can I avoid textile beaches and pools. And I definitely feel uncomfortable wearing swimwear (clothes) in the sea or swimming pools, it seems quite daft to wear clothes when in water.
Ever tried nude dancing? Now that is real fun and definitely adult, but you need to find a liberal club to have the most fun.
Try Cap d'Age in the south of France. This is a true nudist city. Beaches, housing complexes, hotels, resturants, shops, banks, all nude.
But the USA is extremly prudish when it comes to public nudity. Europe is far more enlightend.
Have fun - the best is without clothes.
