It would be far better to attempt to get to the root of your fears and address them now rather than waiting for some imaginary "toilet heaven" in the future.

Like other posters you are projecting your own toilet anxiety onto others - you imagine that those around you are disproportionately interested in and actually seeking to hear any noises you make in the toilet. In actually fact for the overwhelming majority of people the opposite is true - good manners and politeness, not to mention questions of taste, mean that most of us have no interest at all in and actually would rather not hear the noises others may make in the toilet.
