Since it's okay for wives & girlfriends to snoop, how about if men do it too?

Most of the other responders are missing the point - her snooping is what is called a fit test or a sh!t test: she's (hypergamously) testing you on how you handle and respond to her, not necessarily on whether you're actually hiding something or not. And responding in like kind (snooping her stuff or challenging to do so) is a failure if not handled in this context.

Understand what a woman does, not what she says. The chewing gum example: men see women like chewing gum - the more its been in another man's mouth the lower the value if not outright repulsive; women see men also like chewing gum - the more its been in another woman's mouth obviously the better it is since so many women want it. Her instinct to snoop is to see how high of value you are to other women (how chewed is your gum), although what she *says* about it can differ.

This is a test on your fitness to the relationship, not necessaritly a challenge to individual privacy.

Of course if she's BSC then all of this is moot.
