Yes they do! I'm a boy, and I can tell you they do.
If you're that easily aroused by 'a glimpse of stocking', perhaps you should seek therapy -- or move to Riyadh.
Maybe? I'm not sure I find this convincing.
Do you seriously think boys in sub Saharan Africa or Polynesia walked around in a permanent state of arousal?
Sexual arousal is part of the male visual process. Its easy to trigger resulting in an energetic decision process in males. You are suggesting that taboos generate this? All of it? That is difficult to believe. First, you'd have to explain why men are stimulated by porn rather than by grass and trees. Why are men not attracted to...stoves or clouds or darkness?
But what men find arousing is culturally determined. In the Caroline islands (South Pacific) topless women in school or the mall wouldn't raise an eyebrow, but try venturing outside in a short skirt or cut-offs, and people would be texting the police. Naked thighs are strictly verboten.
So just whom do you suspect of establishing this strictness? Because I only see the change as one of fashion and not that of some controlling entity.
"Controlling entities" follow fashion. They pander to the "community standards" of those who sign their paychecks.
Actually, the web page featuring this 2015 map says that the "green states indicate there is some degree of topless freedom.'" Which is why I suspect it can show Colorado green despite the fact that toplessness was outlawed in Fort Collins.
Of course. The ruling referenced by the OP was just a local ordinance. There are lots of local restrictions that aren't reflected by state or federal law, and even where there aren't specific laws against toplessness, you can get hassled by local authorities.
