Difficulties with wearing a device? discussion

(I wouldn’t be shocked if this has already been covered in depth somewhere else, but after doing some digging and not turning up the answers I need … please point me in the right direction if you have a link!) Ever since starting my 24x7 chastity routine on October 3rd, I’ve been wearing an HolyTrainer v3. For the most part, it’s been quite comfortable. The main issue is occasional discomfort when the tip of my circumcised penis slips through the end slit a little too much and gets rubbed by my trousers while walking — ouch! Lately I’m considering moving to a bespoke metal cage (the continuous wear has worked well for me and my husband seems generally okay with it) — mainly for hygiene and sturdiness reasons, since the seam on my HTv3 tube has come apart. I’ve started testing out Chinese A272 as a trial run. What I’m noticing is that the extended slit at the front makes it easier for my penis to poke through — even though this cage is slightly longer than the HTv3 (small tube) model I’ve been using, which usually fit my soft penis just right. I prefer an all-steel design over a tubular one (at least towards the tip) primarily for cleanliness reasons. Any advice on how to shield the tip? Or do others find that certain custom cages don’t suffer from friction or chafing with a cut penis?
