have to agree... several years ago went to a nude campground- I went down the (well know) 'sex area' (aka the trails). A guy and I went at his (me fucking his brains out on a bench- lot of fun). A group (naked) gathered....jacking off, playing around, really added to the mood, sweat, smells, etc. Then one guy walks up, in shorts, reaches into his shorts, playing with himself. It was like rap music at a classical conscert. I stopped mid-fuck and said 'do you mind?"...nothing...several times, mood dying he said 'someone might walk up'- I explained this was a privately owned gay camp ground, private property, etc..etc. Either you leave or we move.
"If you wan to watch, go rent a fuck movie at home- you join in or leave"...sheesh.
