<human>: When I gave my supervisor my cash drawer to count I had my phone in the drawer.  I walked away and came back to find her with three other co-workers huddled around my phone obviously amused by what they were looking at.  

The last pic I had taken was a dick pic requested by my girlfriend.  My supervisor hit the home button (iPhone) but I was able to tell the only app that was open since I had used the calculator app to count my cash was the photo app.  

My supervisor denied any snooping and said she "just wanted to see how an iPhone worked".  I'm not sure how to react to this.  My main beef is with my supervisor for A: Going through my phone and B: When found dick pic, told others to come look at it as well. This is someone I report directly to and feel totally violated.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My supervisor showed others dick pic on phone, I know it happened but she said she didn't.  I feel violated.  How should I proceed. (besides enabling the password on my lock screen)
