It happens. I got bitten on my manhood by a dancer one time. Through my jeans, uninvited. Left bite marks. It was truly terrible. I hope she had all her shots. She offered me free dances for life, but my gf at the time put the clamps on that.
about 2 weeks after that a buddy of mine got his eye slashed open by a dancer doing a spin move on pole. Her stilleto caught him on the eyelid. He bled everywhere.
For a while we joked about making a mockumentrary entitled, "when strippers attack!" Never got off the ground. Maybe this guy in south florida will bankroll the project. I can't wait to see the dramatic recreations.
