BBC NEWS | Magazine | Can people unlearn their naked shame? I havnt read it myself but though I would share.
There's no shame, just peer pressure more than anything. A male human body is something to be proud to possess! If anything it seems that it's a trend towards an infantile and pre-pubic look that is more "fashionable".
The video in the link is about shaved versus unshaven in terms of attractiveness. I personally am very turned off by body hair on the chest, upper abdomen, and back along with the upper thighs and rear. Sometimes arm hair can be an issue too. The article, I have to agree with the previous posters.
