When you get hard, your scrotum tightens, which may make your balls appear to disappear or pull closer to your body. This is a natural reaction to changes in temperature or arousal, as the body works to maintain optimal temperature for sperm production. It's completely normal and indicates your body's reflex to protect and regulate the temperature of your testicles.
