Well unlike most people, I have no issue telling anyone or caring if anyone notices.
Wearing in public is something I do because I already have a diaper on, I do not go out of my way to diaper myself then go to public places, or visa versa, but if I am already wearing a diaper I do not go out of my way to remove it to got out to public, unless I need to change.
That being said, if someone notices, and then makes questioning eye to eye contact, I smile and shrug and continue on my business ( if I am talking, checking out at a register, or simply walking pass someone in an isle at a store)
Never have I been questioned about it, teased, or even felt judged for it in any of these scenarios.
Finally the few times that I have been, it has been mostly by friends or relatives that disdained the idea of it.
To those friends, I have explained that I do not understand why I feel the need to wear them and appologize if it makes them fill aqward or anything, those friends have never cared, and few have ever brought it up again.
The next group my family, they just do not understand because they find it socially aqward, and because they do not want to be assiated with it, or have to explain it to anyone because they have a hard time dealing with social aqwardness. I imagine this causes anxiety about the subject, which builds up stress and they don't really understand how to cope and end up simply agressively rejecting the idea.
I can not hold that against them, and I do not.
I simply avoid the topic and if it ever comes up, I attempt to change the topic, or make it equally awqard for them by bringing up personal intimate questions.. normally parents and family hate answering those and change the subject for me.
But, co workers, friends, class mates, as from my exerpince has never once cared, and I have never once lied about why i wear them.
Edit, the first time someone found out that wasnt family they didnt tell me.
But later while i was wearing a wet diaper, they called me saggy butt.
I felt really embarrassed he however never mentioned it again.
