In order to be a great burlesque performer does one need to be able to do acrobatics/gymnastics, or be very flexible? I can dance (I have had some training), but I can't do the splits, cartwheels, aerial hoop, etc. Will this hold me back as a performer?
Just do what you do and do it fiercely. I'm partially physically incapacitated from a series of car accidents, but I don't think anyone knows unless I tell them.
