I posted this comment on acesontop's post as well.
We see a repeat of this topic from time to time. The determination of what is 'indecent and should be covered' is definitely a cultural issue.
We have to remember that up until the mid-1930s men were REQUIRED to wear shirts that covered their nipples too (USA), even at the beach men needed to wear shirts. It was the famous Coney Island protests by men willing to get arrested to make the point it was 'ok' to show their chests in public that finally got a ruling in NY to start the ball rolling nationwide.
So here we are 80 years later with women fighting the same battle. Did we forget women's ankles used to have to be covered, then allowed as long as those pesky sexual knees were covered, now it's up to thongs and X over nipples. It's hard to fight multi-billion dollar industries profiting off of covering and or 'teasing' out boobs and nipples. [ Victoria's Secret]. So the world continues to shame them to be covered.
There is a difference between nudity and sexuality. Anything can be come sexual in context if you want it to be, once that mindset is activated, then sexual desire/thrill follows.
It is what it is. :-)
