Yup. John has hit the nail on the head.
The nude beach experience was the 'big liberator', and it did trigger the hunt for sex for most of us. Some dudes did not jump on the wagon, confirming that the decision on how you wanted to live your life was eventually, always yours only.
For the rest of us, the 'nude beach & sex in the bushes' experience started a new chapter in our lives. Hopelessly str8 dudes went on to conquer the hearts and other, probably more desirable body parts of their future girlfriends, footing a few open-air cinema tickets and ice-creams, etc.
A few other dudes got very quietly organized into our private coteries. Having a safe place of your own was a very major advantage, too.
Though we are talking eos of times ago, when no one knew of Airbnb, local folks in a very popular tourist town were renting rooms to the passing/vacationing tourists. The few guys who did not have a safe place of their own, pretended to be, well, 'passing tourists', and got to lock the door behind their bedroom and experiment... A friend once told me that this was the money best spent in all of his life...
Life inevitably kept moving on, as it always does. But some folks got the best of it, and the others, well, not so...
