Am I too tight?

Whenever my boyfriend fingers me and goes in and out , it doesn’t feel good. It hurts! Whenever he leaves his finger in there and starts moving it around , it feels amazing ! I’ve seen my vagina and it’s very small. I’m still a Virgin , btw. It’s super tight or something. I’m afraid that when I do have sex , it’s going to hurt really bad ! Is this normal or should I go to the doctor and ask ?? 😕

If anyone else has/had the same problem , PLEASE give me advice !
