I don't care about pictures or videos - he doesn't do it in front of me, and if he does, it's just to provoke me (in a humorous way). I do get annoyed if I catch him looking at people walking by when he's with me. I think that it's normal to do it, but it shouldn't be obvious.

Have you told your husband that you don't want him to do this in front of you or let you know he's doing it?
