I would dare say a kick to the balls would be worst. To be fair as a male prostitute I am kind of biased though for I need my balls in my line of work. I do recall this one time though I had this john who wanted to kick me in balls while I ate ice cream at the same time and I had the brain freeze moment and for some reason the pain in the head did seem more pronounced than what was going on with my balls.
