Hi Slipmeuk,
Had a great time and was very lucky indeed, on the site, a couple in a caravan facing me made a point of leaving just the curtains / blinds facing me open and made a point of ensuring I could see as they were having fun, once they could clearly see that I was watching and aroused they beckoned me over and I was invited in to join in the fun. I would not bank on that happening though, most times couples keep the fun confined to the beach, though quite often if a couple take a liking to you, they will ask if you are going to the naturist beach and hint that you should come over to them if you spot them, I have only been invited to fun on the site a few times, mostly early or late season when its quiet.
The beach on the other hand is where the fun is almost a cert, so long as you are not pushy and do not simply follow couples around or hover too close for too long. Couples will soon let you know if they are interested, 'meerkats' those that spot couples in the dunes and hide behind a hill or grass, continuously peeping over, are unlikely to be invited to join them, better is to simply make your presence known, then settle a reasonable distance from them, you'll soon know if they are interested. I stayed over for 4 days and left very happy indeed, lol. Though as I say, just being at that beach with lots of like minded naked folk is brilliant, any fun is an added bonus.
So long as the weather holds out, I will be going as often as possible, probably every other week until well into September, possibly beyond. I am off over there tomorrow (Sunday 5th) for a few days, forecast is not brilliant, but it ain't cold, plus, most couples have their stays booked in advance so should still be lots of folk about.
Do get over there if you get the chance, you won't be disappointed.
