Dick picks

A couple days ago I went to take a picture on my husbands phone. When I opened the camera (iPhone) I saw a picture of his dick in the last photo taken square. I was immediately upset because I hadn't gotten a dick pic. So yes, I started snooping. I went to the deleted pics and there were 17 pictures he had taken of his dick on two separate occasions. What is bothering me the most is some of the pictures were taken at work in a public restroom. Who does that? I'm sorry I am all over the place, but this is eating away at me. Why would he take them if they weren't meant to be seen by someone else?! I haven't said anything about it to him yet, but I know I have to. It is all I can think about. What would you ladies do?
