Difficulties with wearing a device? discussion

Ouch, ball trap devices aren’t working out for me. Remember that measurement with the string? The biggest backring from Holy Trainer measures 7 inches. But my space behind both nuts and sausage is actually 9 inches. I have purchased and worn the largest HT and Birdlocked models. They weren’t large enough; I even ended up in the hospital with epididymitis, which took weeks to heal. Not blaming the devices themselves, they just seem too small for me.:| ALRIGHT I’ve started researching belts, but they are ridiculously pricey. Are there other kinds of devices besides ball-traps and belts? Has anyone found a non-metal belt? Do belts put less pressure on the nuts? Meaning, will that 9-inch circumference still cause trouble with a belt? I really want to be able to give my key away; hopefully you all have some tips to help me get back behind the lock. <3
