Tape would help you, or most likely would.

Just dance with me baby and don't worry about any slips hon.

Now to be less facetious...

I wouldn't know such things being a guy and all..but perhaps if you were to wear some tight spande undewear or short shorts under the skirt? Perhaps trim them to not be so noticeable when your skirt flips up? See..somehow I don't imagine dancing around with tape down below would be comfortable. And sweat? Icky-poo sicky you know? And removing it? I'd not want to be you in that situation!

Let it hang long and loose under your skirt ... soooo sexy. Keep your knees together like a proper lady when you sit unless you want to flash your lady meat.

as a man, its hard to give proper advise, a lot of the posts here suggest doing nothing and let it hang out! this would be fuckin hot, but i'm guessing thats not why you asked?
am i wrong when i say there are under garments that accommodate for cock and balls?
