The thing about taboo things is it tends to be the things that are taboo that excite us. At one time in society when woman wore big dresses and covered up their ankles revealing their ankle could cause men of that day to nearly blow their wad. That has changed over time, yet now revealing a breast can be extremely arousing unless you live in an African or Indigenous tribe where woman are bare breasted. In those societies exposing the breast is not a big deal. In some societies where the nipple is censored the breast may not illicit a lot of arousal but adding a nipple just might. So in a totally free society what would our new taboos be? Would we be intentionally dressing ourselves up before sex so that we had layers of clothes that our partner(s) must try to remove. Could our sexual encounters become something much like a magic escape act? Could we instead be looking for even more extreme taboos to arouse us. At the most of us cringe at the thought of Golden Showers or people shitting on us. What if that became the norm if sex was completely open?

I suppose one place we could visit would be long term nudists colonies. See how that impacts their arousal conditions. Yet a nudist colony may not be 100% liberated either, so even that would not be a perfect experiment.

Interesting topic... thanks for posting it.
