I feel like there's something wrong with me

I don't know what's wrong with me but... I seriously cannot fix anything inside of me, not a finger not a tampon, nothing! I went to my first GYN appointment and when she had to do an inner examination she tried to put a qtip inside of me and it hurt so bad i started crying. I just don't understand why I can't fit anything inside of me. I want to be able to explore my body and make myself feel good but I just hurts and I don't know why.
