I was 18, the weather was glorious and my girlfriend and I decided we would have a day at the beach.  We had heard good things about Studland so off we went.  We parked up the car on the ferry road car park and walked around the headland.  At this point it's worth pointing out that we knew nothing of Studlands naturist credentials, in fact back then I don't think it was endorsed by the NT as such. 

We settled down near the entrance to Poole Harbour and after a while went for a walk in the dunes, suddenly three guys came running past, all completely naked, the girlfriend ddin't know where to look, it was a combination of looking away and trying to take in all three at once.  At this point we broke back down onto the beach... Everyone was naked, even the women 😀  I thought I had died and gone to heaven, until girlfriend accuses me of setting her up, I protested my innocence.  She didn't seem entirely convinced.  So we went back to our stufff talking about what we had seen.  A few minutes later we had gathered up our stuff and joined everyone else.  We spent years going there after that.  We eventually married and then, like so many divorced. 

My second wife, (love of my life) said that there was no way she would go to a beach llike that, "It'll be full of weirdo's!"  That didn't last 😉
