I banded my neighbors husband for her some years ago. Squealed like a pig, it was good we were out in the country where no one could hear. He was begging to be cut free, but the balls belonged to his wife, and he had no say in what she did with them. It was fascinating how fast and how black his balls turned. After two days we removed the band, and his balls were swollen to the size of soft balls. I would have left him banded, but his wife wanted to hurt his balls more before taking them completely away. The next week we re-banded him, and his balls fell off about three weeks later. He is a doctor, so was able to take care of himself.
