I've seen a few parties like this that if they weren't orgies, they would certainly qualify as "living porn", and others where practically nothing happens at all. So much of that stuff depends on the atmosphere, people's state of mind, being comfortable, etc. Just being naked doesn't give anyone clearance to begin touching others. In my experience and observations, people tend to "ask first" before touching other people. Once hearing what their boundaries are, then they can go further.
i like to cuddle...then whatever else happens but thats cool! nudity [especially in a nonsexual context] REALLY SHOULDN'T be as big a deal as people make it. have fun!
if I have friends and friends to visitam I just naked. and also if I'm friends at friends, I am naked. often they themselves get also from the clothes.
