Men should cover their ass..... The 'thongs' they use today wouldn't even be allowed in a 'public' swimming pool'...
I think this kind of trunks are the ideal. Compare Ronnie and Arnie - the latter one's are enhancing the physique better (the parts of a physique that bb should be all about...). I think the trunks Arnold wear are more 'aestetically pleasing'... If you doubt that - try to imaging Arnold on stage in one of those trunks??
