it depends on a few things. 1) how big the guy is. If he is big it will hurt more. 2) how much foreplay you two have done. If you do a lot you will be relaxed and wetter. Which will help the process a lot. 3) how slow the guy is going. My first time was slow so it hurt a lot.
mine was like a 6 or 7. It hurt but it was manageable. After a while I got over it. It feels a lot better after a few minutes. But for the first couple of times it will be painful in the beginning.
hope this helps!
