I live in a country with nudist beaches, but young women and teenage girls also go topless on the normal beaches.
If, say, a boy ended up staring at a girl with her tits out, would he be the sexual assaulter (for looking), or would the girl with her tits out be the sexual assaulter (for exposure)?
This has happened every single time I've gone to the beach. In fact, when a girl took off her top nearby me and I saw and looked (momentarily) she smiled at me. She kept smiling at me whenever I walked by and I tried not to look at her massive boobanies.
Again, this was not on the designated "nudist area".
Of course, such a thing is unconscionable in most of America ("land of the free").
European "sex/morality laws" may have their own issues (largely due to them increasingly trying/being forced to imitate American standards), but they're still miles ahead of heavy-handed American puritan prudishness.
I genuinely think most Americans' heads would explode if they walked into a nightclub here and saw what goes on.
"...I have a hunch that children raised in America, where sex is “dirty,” are more likely to have problems with sex and their bodies than those in Europe. I suspect there is more violence associated with sex here than there. I have a hunch that the French, who have as many words for a kiss as Eskimos have for snow, enjoy making love more than we Americans do. I like a continent where sexual misconduct won’t doom a politician with anyone other than his family and friends, and where the human body is considered a divine work of art worth admiring openly."
