Testicles hurt when I get mad

My best guess is that getting mad might raise your blood pressure and make the pressure increase inside your balls and then they ache. Or it could be that your balls pull up close to your body and stay tightly hanging inside your sack up high and safe as a natural fight or flight response to danger and anger. In a fight you'd want the balls pulled up tight against your body to protect them best when you're busy fighting and keep them pulled tight and out of harms way. Low hanging balls swinging around loose in a fight are too easy of a tempting target to hit or damage. In a flight response to escape from danger, you'd want your balls hanging high and tight against your body when you run fast to keep the balls from swinging around bumping your own legs and getting hit when you're running away from danger. Also, the adrenlin you feel pumping through your body when you get angry or frightened is designed to prime your body to be extra for fast action to carry out a fight or flight response to any dangers too. Men are still animals, just animals who think we're more advanced. Tell that to our balls and penises lol.
