Guys, It’s it normal for guys to be naturally possessive?

I have this one friend, let’s call him Bob. Every time I go talk to someone else, Bob gets mad and says he doesn’t want to talk to me for literally no reason. When I talk with Bob 1 on 1 he doesn’t get mad unless someone else joins the conversation. He generally doesn’t get mad if it’s a girl that joins, but every-time a guy joins in, gosh it’s a nightmare. I don’t know if this is normal or not since I don’t have many guy friends.
