Is there something wrong with me?

Asking medical professionals or anybody with the same experiences. I have been trying to have sex (still a virgin technically) and it is way too painful! I'm talking not even 2cm in and I'm crying and in agony. I am aware that it might hurt the first time but it should not be this bad, I do have a high pain tolerance. I've been looking into possible vulvodynia, vaginismus, or endometrius(?) and I'm really not sure. I've tried to have sex 4 times and tried using tampons twice but it is just too painful. Any thoughts??
