Moving balls

Do you guys ever feel your balls moving. Sometimes when I’m laying or sitting down I can feel my ball draw up and down and tingle with out me doing anything to them, is this normal

Yes its normal, well the moving is. I’m not too sure about the tingling though. You might want to get that part checked out.

Kids these days don’t get enough information in school about how their bodies work.

Which muscle

My balls like to play pool, they just haven’t figured out which pocket to go in.

Your scrotum is lined with muscle I think (Dartos muscle?). During temperature changes, it will contract and expand on its own.
