twitching under my testicles

For the past few weeks ive have a twitch under my testicles. everything feels normal no pain or anything just a "twitch" lol what could it be?

Skip the Spinnin/Cycling classes at the gym for a while and see if it goes away.

I've had that once or twice. It's just like that damned twitch you get in your eyelid that no one can see. I've had a twitch in my middle ear for a week, that was rather annoying..
