Is there something wrong with me?

Okay so this is something that really bothers me and I was wondering if it has happened to anyone else before. I can not insert a tampon. I have tried everything. I’ve even taken a mirror and tried to watch myself do it. I know this sounds stupid but I honestly can’t even see the opening of my vagina. Is it possible that I just have a small opening? Have any of you experienced this? Do I need to go to a gynecologist? Please help!
