Well, the "stamin pump" is the way to go, but the ring just doesn't seem to hold it. What ring do you guys recommend? Let's hear about your experiences.
I guess you are talking about the ring of the pump that you slide off after erection? Use a regular cock ring like the Titanmen or maybe even the Penis Pump Erection Enhancer
Even using regular C-rings I have never been able to keep the bigger size for too long.
