Chastity and orgasm denial discussion

I was giving my CB6ks a try with what might have been an overly eager effort. After spending a day or two dialing in the fit, I wore it for 24 hours straight. When I finally took it off, the front of my scrotum looked sad and red, on the verge of blistering. Now I’m letting it heal before giving it another go. That was over seven days back, yet I still notice subtle signs of that initial injury—itchiness during daylight hours, heightened sensitivity in that area, and a specific time each day when it definitely hurts as if some burning sensation remains. What have you all found regarding injuries with these devices? Also, on its own, how much time does the scrotum need to expand, harden, and adapt? My key holder is very cooperative and kind; I just can’t surrender my keys until we figure out a safe routine.
