iPhone asking Trust Computer EVERY $%&! time i plug in!

[tys]

My iPhone recently started asking me if I trust my computer every time I plug it in. I say YES every time and then everything works fine, but next time it asks again. I've tried rebooting everything, fixing permissions, updating iTunes, I updated OS from Lion to Mtn Lion, de/re authorized computers and devices in iTunes, logged in and out of iCloud and iTunes accounts, "reset all settings" on iPhone, different cables, nothing will make it stop! My iPad 3 and iPad Pro don't have this issue.
It's not causing any problems that I can see other than really annoying me.
Any suggestions would be appreciated. It seems like this is common on iOS 7 and Windows, but I'm using:
iPhone 6 Plus, iOS 8.4, Mac Mini early 2009, Mac OS 10.8.5, iTunes 12.3.2.35

This happens to me on every single computer I use, every single time. It is annoying. I'm interested in what folks say that be done to resolve it.

Update: I think it may be related to my USB personal hotspot feature being turned on. Perhaps a safety feature since you could potentially suck down a lot of data if you didn't realize it was tethering. I switched it off and it so far is has stopped asking!

Interesting, but I don't have hotspot turned on.
