Among people you are close with but I guess I'm talking about partners really. My boyfriend has looked through my phone before (to look at my pictures) without my knowledge and while I was a bit embarrassed I don't actually care. I've looked at his. Granted I'm a nosy person.
The strength of feeling on this is baffling to me... what is it actually that's on your phones that you want so deeply to keep private? For me it doesn't go beyond embarrassment, and if it did it would signify some kind of wrongdoing tbh.
Is it all one big cheater conspiracy? A woman will post on here suspecting her partner of cheating and God forbid she lets slip that she looked at his phone or the entire thread will become about how INSANE she is
