I completely agree with you in that we are shaped by centuries of social habits and control which explains why it feels wrong to expose ourself around strangers.

But to answer your question I personally wouldn't do it because, as a man, I would get arrested and probably put on the sex offenders list...

Now to be perfectly honest I suppose I also prefer keeping my body to my wife rather than exposing myself to strangers anyway.

I do understand the liberated feeling though. This wasn't uncommon back in the 60s.
Fair play to you.
