Guys: Would you hit another guys balls in a fight?

Just curious. I most likely would not. But, if it's kick a guys nuts or get beat up, I would kick his nuts. I feel kinda like a wimp when I think about this, but what if a guy is bigger than me? It's not like I go around fighting people anyway, I only fight if I'm the good guy in the situation and he is the bully. So, would you hit a guys balls in a fight?
