I was having sex with a lovely lady the other day. At one point I pulled out, she squeezed, and there was a bit of pain due to the ring. No big deal. I looked at it and didn't notice anything and we kept going. Pull out again later however and the ring came out. The ball was nowhere to be found. It turns out it had gone up my urethra and came out when I finally got off.
So uhm, yea, does this happen to you?
