Personal ads - Looking for a keyholder or sub? discussion

Alright, let me lay this out. I’m new to the world of chastity and want to observe how my body handles a few months under its stress.

Although I have devices like a time safe that keep track of things on their own, having someone physically hold one key would be useful for emergencies when medical access is needed. This means I need someone based in the US as my Keyholder. The dynamic shouldn’t involve any submission or dominance traits—just straightforward interaction: sending an envelope containing the key and a scheduled return date, along with contact details should anything urgent arise.

I’m open to suggestions from anyone willing.
