I know this sounds a little weird but it's true. Whenever I do any sort of exercise, (even walking at work) my testicles are no longer hanging. They rise up very tight and start to cause a dull ache that goes away a short while after I stop exercising. This has been going on for about 5 years now. What could be causing this? I have researched this a lot on the internet but have come up with nothing. Thanks a lot in advance. Any suggestions are appreciated.
