Ballet
Ballet is a very stylised form of dance, usually designed to tell a story. It comes from the Latin ballare (to dance).
Some people have a fetish for ballerinas (female ballet dancers), partly because they traditionally wear skirts that are short and stick out, allowing views of their legs right to the top. It was customary in 19th century Paris for operas to incorporate a ballet so men could admire the dancers and possibly arrange a date with one afterwards.
Male ballet dancers usually wear tights, showing a male bulge. It is said that many male dancers are gay.
Because ballet training is very classical in nature and teaches a great deal about balance and poise, it is not only taken by those wanting to be ballet dancers. Many top performers in martial arts have some ballet training. The exactitude and requirement for balance and fluid movement also help in other forms of dance and many popular dancers and actors of both genders have at least a basic ballet training. It can also be good to help teach a slave poise and gracious movement, making them more pleasing to their owner's eye.
