That was amazingly homoerotic for TV

It certainly was and I was amazed (and completely turned on) when I watched this video. Mind you, that was nothing for the Ancient Greeks - in the pankration, they wrestled naked, oiled and in a mudpit, so it is hardly surprising that it was the number one sport for the all male audiences of the day !

I blame jewish-christians for that involution in shyness xD

You might be right there. I sense that the Greeks had a lot of fun !
