It definitely does happen. Typically however everyone puts on a tons of clothing to try and draw out the point of "exposure" haha. It good fun however, people people grab pillows etc to hide constant exposure as that can be a bit distracting lol. It would be more fun if it's spontaneous so no one can prepare with layers upon layers of clothing or the rule "only what you typically wear and accessories & shoes don't count". Men don't wear many so they are at a disadvantage compared with a fully laden lady wearing heaps of jewellery etc.
