Chastity and orgasm denial discussion

Greetings everyone. I’ve been wearing a CB6000s since April 1st, but staying locked all night is tough for me. Usually, I lock up from around 6:30 AM until somewhere between 11 PM and 1:30 AM daily. I’m currently saving money to buy a custom metal device, so the CB is my main option right now. The issue is that my “boys” are being difficult. Every morning they sit high and tight, but by evening they sag down loosely as if I’ve been drinking beer all day. This means I need a 1 7/8 inch A-ring in the AM, but it gets too loose later on, so I swap to a 1 3/4 inch ring for mid-afternoon onwards. Sometimes I even have to adjust the spacer slightly. Interestingly, while I can slide the disassembled 1 3/4” ring onto me easily in the morning, my boys won’t pass through it smoothly until later in the day. By evening, they glide right through… quite strange behavior, like Dr. Jekyll and Mr. Hyde!;) As I plan for my metal device and try to figure out the right measurements, deciding on the A-ring size is tricky. I hope that once I have a custom piece, I can wear it 24/7 without needing to slide my boys through a 1 3/4 inch ring every morning. However, I worry this daily fluctuation might cause problems. Has anyone else experienced this? Is it because I’m not staying locked around the clock and just “reset”ing the testicle position (and related tissue) each night? If that’s the case, I’ll probably have to take the plunge anyway since wearing 24/7 in a CB6000s isn’t comfortable enough for me long-term. My main concern is getting incorrect measurements for my custom device, as adjustments cost extra cash, but they are being… uncooperative.
