Before I started wearing protection I found the same in that at home it always seemed worse. I think there were multiple reasons for that in that I also tend to wear sweatpants/tracksuits around the house and denim being tougher maybe it takes longer for the smell to be so noticable. Also, due to my dribbling issues, I'd always save jeans for just going out so I was probably spending less time in them as I wasn't wearing them for a full day. Plus, I tended to under-hydrate when out so that I wouldn't need the toilet. At home, I'd stay hydrated.
No change in belts etc. Re the suits, I attribute it to the fact that you wear them for multiple days. Before we had to wear suits at school in the sixth form (final two years) I'd wear a new pair of school trousers each day but then I went down to one a week when I started wearing suits as they were dry-clean only (looking back, it must have cost my parents a fortune!). I certainly felt the added pressure to keep them dry and would dread every time I went to the toilet. Plus, come Friday they'd smell pretty bad and I was really self-conscious. Looking back it's mad that I spent two years being really anxious about it. I guess that's it when you're a teenager - easier to suffer in silence than have an awkward conversation with your parents.
Once I had to wear suits to work the same anxiety hit. It's also when I figured something was up. I had a colleague who dry-cleaned his suit once a month or so whereas there was no way I could get that type of wear out of it. Around that time my IBS really flared up and I started using adult nappies for that overnight as a precaution (I'd had a rather embarrassing experience at a hotel and figured next time I had a flare up, I ought to take precautions). When I was wearing them they obviously absorbed any after-dribble leaks and it was great to finally have dry clothes. I then started using male guards on a daily basis (was too self-conscious to wear anything more substantial on a regular basis back then).
My issues have changed in that due to long-Covid symptoms my bladder issues have gotten a lot worse and rather than post-void dribble my main issues now are containing floods as more often that not, I can't make it to the toilet in time. I'm also still waiting for a urologist appointment (had one booked last Easter and I've been waiting ever since due to Covid) so don't know what's up.
