hello everyone, I’ve been reading here for ages but this is my first time posting. I own a KHD X3 Espresso made with 3-D printing and wanted to ask if anyone has used it. My keyholder and I are new to chastity play. I’ve had several successful locks of about 48 hours without problems. Now, she decided we’d try for five days, and today marks the fifth day. When I woke up this morning, I felt something was off—a stinging sensation that I hadn’t experienced before. She took off the cage to check and found a cut under my penis, right where the shaft connects to the glans. Does anyone have advice on how to fix it? Could 3-D printed cages be prone to causing this issue? I know many people test out several devices before finding their perfect fit, but has anyone else dealt with something similar and could recommend a different cage or share some tips?

i haven't come across that specific model before, though i really enjoy espresso coffee.
