I honestly don't understand some of the reactions that pop up in topics like this. Why is it that when someone suggests an addition that could have two sides I see people assuming it's got to be the "seedy" side.
The Sims had a dancer that popped out of a cake and TS3 had party dances that appeared at bachelor/bachelorette parties and both kept their T rating.
Along with entertainers pole dancing it is currently a fun fitness alternative. There are three studios within a few miles of where I live and believe me I live in a very conservative city.
