Tore my vag 1st time- helppp

Francesca

So I tried to have sex with my boyfriend of 4 months.(F18 and M21) It was both our first time but his dick wouldn’t go in and then I felt a bit of pain when he tried to put it in and my perineum tore like just under half a cm. I’m now a bit anxious to have sex because I don’t want it to happen again.

Is this normal?

Do I need to see a doctor?

Does anyone have any clue what happened to make it rip?
