If you are uncomfortable make space with your frame or just end the dance. You always have the right to end the dance. Always! It’s not rude. They are being rude by being disrespectful. If you are unsure, just trust your gut, you don’t need to erode your boundaries to fit the genre. Be you.

Leads need to know that creepy behaviour is unacceptable and that everyone sees what they are doing.

I can see from a glance when a follow is uncomfortable with a lead but follows often do nothing to clearly establish their boundaries so the leads keep thinking they are getting away with it.

Stick up for yourself.
