bah, if it's ugly, just don't look. Nudist are usually ugly, it's well known. Intercourse in public on purpose however is more than mere nudity. It's intrusion in your personal life just like a wanker on the sidewalk....
Well said Michel. I haven't been able to put it into words before, when accused of being an uptight western prude....but that's the difference. There is nothing liberated or evolved about it. It's inconsiderate, exhibitionism....not nudity.
