Don't worry. Everyone is a bit nervous the first time.

So you want to see what it is like at a naturist site, go skinny dipping, walk naked in the woods, sunbathe on the lawn and picnic nude in the sunshine, (perhaps it is on your 'bucket list'). But your partner is unsure and frankly you are pretty nervous too.
Many people are worried about their 'wobbily bits' because we are constantly shown images of 'perfect' bodies.
But you don't need to be afraid. As far as science can tell, human beings are the most wonderful things in the cosmos and you are one of them. And the best curve on anybody's body is their smile.
So come along, have a swim in the pool. Perhaps have a drink or two in the bar and a chat. If you like it - maybe you'll come again.
And if you don't - well you've tried it and no one need ever know...
