Is it normal for my girlfriend to send pictures to other guys but not me?

Anonymous
So me and this girl have been dating for a few months now and she never sends me pictures on snapchat (regular pictures, not nudes). We always just use the chat option. I've tried multiple times but she either just replies in a text or sends me a picture of the wall and typs on that. The reason this bothers me is because she always sends selfies to other guys and snapchats them like that and not me. She even puts selfies on her story but won't snapchat me, I'm just so confused. If anyone has any advice it'd be greatly appreciated.
