I like to spend time at home in the nude, and even to exercise that way (hey, NordicTrack is a lot more fun in the nude!)
I love the feeling of not having to wear clothes... somehow, it feels similar to those rare days when I've been able to practice silence, not having to say anything (or as my Sensitive New Age Guy friend would put it, "just being.") What a relief.
There are no nude beaches where I live, but I will admit to occasionally having slipped off my swimming trunks and just holding onto them, swimming in the nude, when I was far enough from shore and everyone else, that no one was the wiser.
I did attend a "Loving More" event once where clothes were optional, and a lovely lady invited me to swim nude with her in the pool, enjoying some light touching and caressing, sort of a dance in the water, with the understanding that she did not / would not have sex with someone she'd just met, so that that was all there would be.
When it was time to leave the water, I was hard and standing straight up... and though earlier in the day, I'd very quickly gotten used to being naked with strangers around, it was tantalizingly close to being outside my comfort zone to be completely erect, where everyone else could see.
I wasn't hard at any other point in the weekend when I went without clothes in the common areas, so perhaps I qualified as a nudist at heart, not someone who was just "naked."
My lady is excited by the idea of our going to a clothes-optional resort at some point. I'm not sure the other ladies at the resort will be so excited by her being there, though... they're in for some wonderfully beautiful visual competition.
