Severe Blister, Chafing, Burning, and Itching Issues

So I just completed over 30 days in the Steelheart. I’m out during the day, but I was locked every night until last night. I was doing fine like this, but last weekend decided to push for all weekend, from Friday night to Monday morning, and I ended up getting a bit of a rash. Well since then this rash has spread, it is angry and irritated. There was a sore spot on the scrotum that wouldn’t stop secreting moisture, then it also started itching, and now it has spread a bit to my penis as well. At first I thought it was just skin chafing, but the itching is really bad and it seems to have spread. It also seems to spread worse if I go back in the tube. Currently the tube is sitting in a 10% bleach solution, disinfecting and will be scrubbed clean before I can try using it again, which won’t be for a couple days:( Could we be talking about a metal allergy here (not sure why it wouldn’t pop up right away), or is it possible I have given myself a dreaded yeast infection / jock itch? I do work out a lot too and use a gym, and on top of that to keep the chastity A-ring burn at bay, I’ve been applying moisturiser around the A-ring. And I haven’t been wearing cotton underwear, or anything really breathable, so it’s been like a jungle down there for the past month. I stopped using the moisturiser and the problem is not better, and I started treatment with an anti-fungal, and things seem to be improving. I may look at going the “dry” route with baby powder to soothe the scrotum if this turns out to be indeed the case. Anyone here ever have a similar experience, and what was your diagnosis / outcome? How can I learn to sleep with the belt on without resorting to lubing the A-ring, or is there a specific type of lubricant that won’t cause these moisture problems? I’m okay with taking the belt off before going to sleep if I have to, but I actually prefer to sleep in it for a number of reasons - I like being unable to touch my penis, masturbate, or have any nocturnal emissions / orgasm dreams, and it feels good to cuddle my wife while wearing it. That easily makes up for any minor discomforts, but when major discomfort strikes, I need to either resort to lube or just take the belt off. On the plus side, I can now wear the regular A-ring instead of the anatomical one, which began to press in one very specific area, at the middle rear of the scrotum, and started causing a blister. That doesn’t happen with the regular ring.
