For the skin issue I have found that sprayable Antiperspirant works very well and I use Old Spice Oasis spray deodorant on that area and never get rashes.
Checking in to see what you ordered and if it worked? I bought the one I linked but did not have much luck but have others ordered.
I was also thinking what if you 3d print a mold for pourable silicone. Make it as 2 pieces that join in the middle with vents on the top and can zip tie it together, could even have the center hole print to one of the pieces so it can't move and even have tiny hole for the thread to go through it while pouring.
Maybe looking out for you not to have the embarrassing situations when someone makes a joke about you in a diaper? I say if you can handle that, and wearing a diaper to work will not get you in trouble with the company or worse yet lose your job. I had a small leak one day at work with a spot in my pants, from dribbles and after that I used a diaper . The next day went from just wearing to bed and fun, to being diapers 24/7. I haven't told any of my family, my wife has been ok with it, but it took some yrs.. I do have way less control now and need them, so its easier for my wife to accept them...
Wetset had the same old question on there 20 years ago. I think it's good a new generation that are liking nappies and I'm getting old lol. There are some good threads on there though.
