The way I see it: I was born with no inhibition whatsoever for elimination. Slowly I learned to control it and suppress it except for particular bodily positions, clothing pulled down, etc. So those can be unlearned just as they were learned. It might help to connect with any thoughts or worries about how things will go wrong if you stop inhibiting, e.g damage clothes, furniture, etc. Eliminating those by putting down some plastic might narrow it down to just the unfamiliar body position and clothing position. At one point I put some boards across the toilet when using it so it was more like a chair, to help get used to that when going. I know that at first it was very difficult, and that I became a little adjusted to it, though I'm not sure how effective it was. The point is just to be creative in approaching these learned inhibitions.
