I took a trip to Haulover Beach earlier this year. I had spent a lot of time wondering what it would be like... when I first caught sight of all that skin, all those naked people living freely under the sun, it was pretty fucking cool.
The demographics definitely skewed male and gay (especially toward the end of the day), but there was still a surprising amount of variety, I thought. There were mixed-gender groups of friends, young straight couples, old straight couples, single dudes (many of whom were probably gay) of a wide range of ages, skinny dudes, big dudes, muscle dudes, ladies of all shapes and sizes. I found a surprising number of people really fucking sexy. The average flaccid dick size was definitely above average, I'd say. I saw some nice swinging softies.
It was a really fun and liberating experience. Swimming naked feels surprisingly nice, as does walking down the beach with the wind blowing where it doesn't normally blow. Laying on my towel and reading was really relaxing, and provided some opportunities to casually peek at the available eye candy.
@arkie -- if I were to spot you heading down the beach, it'd take a lot of self-control not to stare a bit, haha, but I guess that's to be expected at a place like Haulover.
