I guess my first time was when I was very young and lived by he sea and when my cousins visited for the summer. We would walk away from the "oldies" and up into the dunes where we would drop our trunks and then run to the sea and back- feeling very brave. This I guess was the start of wanting to be naked. Following the shy years of puberty I think my next real experience was with my wife and we went to somewhere near Hastings - Fairlight Glen I think it was called, where we sat on rocks and swam in some extremely clear water. That must be back around 1975. Is this still a venue? We then spent a lovely holiday in Rovinj (former Yugoslavia) and went by boat most days to Red Island. No turning back since then.
