My significant other is in his late 50's and his testicles are biggest I have ever seen. When he sits down, they bulge out the side of his pants. His penis get lost inside if his big testicle sack unless he becomes erect. He gets a rash down the medial side of his legs from the heat and moisture. I told him he needs to wear tighter shorts or a jock strap to support them. Is this normal or does he have something wrong with him? He is about 75 lbs over weight.
