How funny. You edited your reply as I was typing and then it updated once I posted!?!??
What happens to the comment that speedos are only worn by old men walking the Agean Sea? Hummmmmm.
The rest of us Americans have got to get our heads out of our collective asses forcing the ideas that the Male Body is a taboo subject and not to be seen. If you show a little bulge then your "gay" or a perv. But the female the more the merrier. We should all be allowed to wear/not-wear ... Show what we want the same. Men have penises, women have tits. Get over it! They're all beautiful in all their shapes and sizes!!!!!
Ok my 2¢ I'm stepping down off my soapbox now.
I think the question was 'SHOULD' a speedo be worn. Not CAN a speedo be worn. Of course, a speedo CAN be worn. But almost every time, SHOULDN'T. Why? Because most speedo wearers don't have the body for it. Just like the saggy old woman wearing a bikini, a saggy old man should save his speedos for the bedroom. If that's his thing.
