Pff, a lot of guys are sissies. Yeah it hurts, but people whine too much about it. I really can't tell if guys are serious when they say they flinch just seeing a guy getting hit in the balls. There's a lot of stuff that's hurt me worse, especially stuff that's damaged my body semi-permanently/permanently. Usually getting hit in the balls isn't a long term (yeah, dull soreness for a little while potentially, but not for like over a week) thing unless you've been hit with an extreme amount of force that would seriously injure you anywhere on the body. Personally I'm fine with pain, it's damage that I don't like, stuff like knee and ligament/muscle/whatever damage. Oh, and getting hit in the throat and temples. Man that stuff isn't cool considering my brain, eyes, and breathing are up there.
