Definition: A Striptease or erotic dance is a kind of erotic entertainment. It is usually a dance where a "stripper" gradually takes their clothes out. Striptease are usually performed in sluts clubs and in some countries, like in the UK, in pubs.
Sometimes it has also been performed in theaters and auditoriums and amateur ones at home. The "arousing" part includes the slowness of the stripper, while men only wish to see naked women.
Some tactics of the striptease to slow down are including more clothes or use the hands to cover the naked body of the girl. Its focus is accompaning the stripping with sexy movements rather than the nudity itself.
In some cases, the performance ends when the girl has taken out all her clothes. Even though nowadays is usual for amateur strippers to end completely naked, this was not so usual in the past due to cultural and legal reasons among many other facts. Those restrictions are for example the dificultness to get licenses and the strict local laws.
The wardrobe of a stripper is also considered an important part of the performance. There's a lot of fantasies about it: stripper with a schoolgirl uniform, servant, policewomen, soldier, etc.
