I think that the older you get and the longer you're into this, the less you care what other people think. At least that's the way it is with me.
Years ago I'd lock myself into my room (or later my apartment) and close the drapes and have my fun. If I went out in public I'd wear my diapers under a long coat or a low-hanging shirt with baggy sweatpants on to hide them. When the fun was over, everything went back into my "diaper box" and then that was hidden in the closet.
Now, if you came over here to visit, you'd see diaper pins laying on the dresser in my bedroom and a pink Nuk 6 pacifier in the head of the bed. If you went in the walk-in closet you'd see my diapers laying spread out on the floor (after a spin in the dryer I let them air dry the rest of the way). My diaper pail is in the back corner, back behind some hanging clothes but still visible. There are plastic pants hanging there drying on the door knob. Sometimes if I've had lots of recent diaper fun and my diaper pail is full, you smell it as soon as you go in the closet. And if I go out diapered, I now just pull a pair of shorts on over them and actually enjoy the fact that they're totally obvious to anyone who looks closely.
The only hold-back for me is that I still have a kid living here but he's now college-age and doesn't go poking around in my bedroom anymore that I know of, if he does this while I'm gone and knows my secret, he's never said a word. If he ever did, I'd tell him "I don't invade your privacy and expect you to not invade mine" and that would be that.
Once he finally goes off to live on his own I think I want to be even more open about it. My wife knows and generally doesn't care. Life is short, and I want to spend what's left of it enjoying who I really am.
