The woman I lost my virginity to did hula hooping. She also did fire-spinning (two fireballs at the end of a rope, swung in arcs). I think she also did fire hooping, which is ridiculous. I took some pictures of her doing this, but most of them were quite blurry (2000's digital cameras weren't good). Using a regular camera, with a momentary exposure time, is probably how I got the second one.
Very few things are sexier than watching a woman spin fire, or hula hoop, in person. Her holding a slow steady rhythm is a massive turn-on.
