I've noticed that etiquette and politeness matter the most in places that people consider the most sexually depraved. Sex clubs, feminist porn shoots, kink dungeons - when run by the right people and with the right environment, you can walk naked through a crowded room and no one will touch you. I'm more likely to get groped on the TTC.
That's the most basic rule. You can look. You may not touch.
