I've been trying to get into chastity full time/long term for years and have about 15 different devices and have the same problem with each, to varying degrees. I get a bad raw skin sore under the ball ring. I've tried different sizes and different lubes but always the same problem. My scrotum is striped with scars at this point from the raw red sores that turn white with infection in just a couple days. I'm high and tight so the ring needs to be tight and/or the gap small or the balls slip out. Plus I'm a grower so at night it tries to tear my balls off (see pic in gallery) causing further skin damage. The most I've ever been able to go is just 4 days! By then it's raw skin with white spots. Sweating makes it worse faster. I've read just about everything there is to read on the web about wearing a device (that's how I found this great site 4 or 5 years ago) but I'm still unable to wear a device long term. I recently got a device with a smaller gap than most and that was helpful but still the problem persists. I'm going to try this one with a bigger ring to see if it stays on and is loose enough to not pinch the skin so badly. If that doesnt work I'm out of ideas, and I doubt it will make enough of a difference to get me from days to weeks/months. I have a full belt on the way that I bought out of desperation. Cheap chinese. After that I'm out of ideas. .
