Dancer's biting or nibbling, is this something the dancer's enjoy?

Lol, maybe if start saying Ouch every time they'll get the hint. May be hard to stop dancers who come out of the blue or are on stage though.

meant to say above "if I start to say" left out the I. I can see how some guys might enjoy frisky females. You have to be careful what situation you are in nowadays though or you could get in trouble. I remember at a previous job a girl pinched me by surprise on my rear and I was trying to get even by pinching her rear. She quickly got away. It was a small company but I wouldn't dare try something like that nowadays.

Of course if you enjoy it then encourage it and tip her well.

Yoda's right. If you don't like it just tell them you have really sensitive earlobes or something, or that biting just doesnt do it for you and they'll get the hint pretty quickly.

No, It's a way for the dancer to entice onto more dances. Just ask them to stop if you don't like it.
