Actually Bhaern the nudity taboo is only a recent phenomenon is western culture, probably appearing over the last 400 years.
The ancient greeks, egyptians and romans, even celtic peoples of western europe had no problem with nudity in either male or female.
The Greeks & Romans exercised/competed in sporting events like the Olympiad all in the nude and the male runners had to use a leather thong/ties to hold down the old wedding tackle whilst sprinting/running etc. Most of the other events were all naked and the only time clothing was required was for protective purposes like the chariot races.
In many celtic society, male warriors would often go into battle naked and more often sexually aroused as they felt it intimidated their enemies although after being thrashed more than a few times, they quickly realised that armour was perhaps a better way to approach a fight rather than standing their waving their willy about.
I can't exactly recall where or when nudity became socially unacceptable in the west but the hight of body loathing came from late Victorian England in the 19th centuary.
In regards to male nude dancing, many cultures did have this practice and male dancers are sometimes regarded as being more graceful and agile than their female counter parts as they are often physically stronger and can move with better ease than a lot of women due to better co-ordination and centre of gravity. This does though come from being a highly trained and professional dancer and most average men today are about as rythmic & graceful as a burlap sack
