People say it doesn't hurt. Those people are just trying to be tough guys. I could cut my finger off and say it doesn't hurt if I wanted to.
In reality, pain can be measured by the amount of response your nerves give to your brain, which is a lot less subjective than 'don't be a pansy, it doesn't hurt.'
I've experienced a wide range of physical pain in my life and I'm not a pansy, but being bit by a 150g BP hurt. Now when I was younger I got a good bite from a hamster, rat, cat... those hurt a LOT more.
