I wonder about peoples experiences with devices that use pain as an aversion to erection. If you don't get hard, you don't cum.. in that sense they work better than most devices, however from my experience using the POI for the CB-2000 was that, while effective, the points were.. well.. too pointy. I felt like I was going to have extra holes in my cock pretty quickly. I'm currently messing around with an idea for a device something like a locking buttplug harness, but with the cockring having teeth. It's an interesting thought, as it would allow the penis to be exposed (excellent hygiene option), but disabled. Unable to get hard. Its a nice idea, but hard to get right with the tools/materials that I have at home. Anyone else have experience with pointy points?
