Guys, Do you think he was jealous?

I showed my boyfriend a picture from months ago, and in the picture was me, the couple who were getting married, and another guy. The first question he asked when he saw the photo was if they were my brothers. I said no. Then next he asked if any of them were my boyfriends at some point. Was he a little jealous?
