Can a vagina be too tight?

Maddie
So for my boyfriend's birthday I gave him head and then he said he wanted to pleasure me (we don't have sex bc I'm a virgin and I'm waiting...) but this wasn't the first time he's fingered me but for some reason it hurt like hell during and afterward,  why would it all of a sudden start hurting now? He was in a different position than he usually is so it went deeper, am I just shallow, too tight or what?
