It's not pains in the stomach. It's my actual testicles. I'm thinking it's just from being pulled on. And, no other rings to try.
I was just saying that's how I know it's too tight for me. We're all different.
If you're not experiencing any pains when it pulls then you're probably ok. But it does sound like the ring is too small if it's forcing you to leak precum all day.
You say every cage you try which would suggest you've probably got a few or have had tried a few and I'm assuming that some of those had different ring sizes from the one you're using now. If you've found the same problem with larger rings then that's odd.
I've had quite a few in the past, cheap and expensive and I've found that larger rings are more comfortable.
