It's your pelvic floor muscles. Believe it or not, your balls are connected to your rectum through your pelvic floor muscles.

See like for me, because I masturbate a lot, sometimes when I take a really huge shit, I end up with blue balls for a couple hours.

Like I would have to massage my balls to make it go away.

But it's really all coming from your pelvic floor muscles.
