Chastity and orgasm denial discussion

Could use some guidance. I’m currently using a HolyTrainer. It’s been over a month of continuous locking, with just a few breaks for full sex before snapping back into place. I stay quite busy both at home and work. The weather has turned cooler recently, dropping in temperature over the last few days. Lately, my testicles have slipped out more than once. Fortunately, I’ve mostly been close to my KH or simply at home, so accessing the emergency key hasn’t been an issue. Is this happening because of the chillier air, or did my scrotum tighten up from constant wear? Would switching to a tighter ring definitely resolve it, especially since we’re aiming for Loctober?
