Re: question about testicals
If you sustain increased blood flow to the testicles for too long by being aroused it may cause a minor condition commonly referred to as "blue balls". It causes discomfort of the testicles and they will feel hard due to an abnormal amount of blood in them. "Blue balls" usually goes away within half an hour and is harmless. If your testicles are sore all the time then you do need to see a doctor.
