Well, I've had many, but one that had a strangely profound effect on me was when I was traveling cross country, by myself, diapered, and I stopped at a desolate rest area for trucks, on a pitch black (no-moon) night, and found a private place, out of view, to disrobe to my diaper & plastic pants, and got the opportunity to just be outside my vehicle, under the Milky Way, for a half hour, or so. It felt like I was visible to all, in the universe, God included, in my most natural state, and it was strangely rewarding & satisfying. Can't explain it, other as described, but I was momentarily free to just be me, in front of all.
