I'm 21, straight male, and ever since I can remember, my testicles have been SUPER-sensitive. Whenever they are touched, whether it be by me or anyone else, I get a VERY uncomfortable feeling. If I get an itch, I can "pinch" the skin a bit and roll it around between my fingers to relieve it, but anything involving touching my actual testicles is out of the question. Forget about my girlfriend massaging them while having sex or giving head, I can't even touch them myself without squirming!
Anyone else share this problem?
maybe you have a swelling or an infection. You might see about having them looked at. A doctor could tell you better.
