I heard that if the testicle was hard-that was bad. It seems to get hard when I'm having sex or masturbating, just wondering if its normal for that to happen? If I refrain for a few days they get back to normal, and they are about as hard as my eyeballs. Any help?
Completely normal. Check your testicles in a warm shower when the scrotum is fully relaxed. You are looking for specific lumps that are often painless. Rarely is the whole testicle involved. The cords and tubes, of course, will feel harder.
