I have often thought of doing this, if it were legal. In a more perfect world, it should be common.
The thought comes, usually in the summer heat, when clothing is a crazy thing, and a burden. I'd be more likely to do it after spending time at a more usual nude activity.
For now, I'll have to project myself into the situation. Would I feel self-conscious, or liberated and comfortable? Would there be an overwhelming nervousness, a rush? Would I just ignore the inevitable attention, or be bothered by it? A supermarket is different from a sleepy little convenience store. Would I feel more comfortable with someone else with me?
How much getting used to would it take?
I have been in resorts walking, shopping, in the bar and gathering rooms, barefoot all over. I have felt a liberation, and a little more naked than usual in the unusual setting. It was good, and fun, then. But that wasn't in a usually clothed environment.
It is a shadow that I would like to face. It would tell me a lot about myself. I would learn that, but would become more comfortable in my skin, to experience myself in my natural state.
