Am I a bad girlfriend if I'm dreading having proper sex with my boyfriend because sex is supposed to be painful?

Still a virgin, but my boyfriend tried fingering me, he got up about an inch. and then I got this sharp stinging pain, like when you haven’t drank enough water and then it hurts to pee. And like a pressure along with it too. I’ve got a really high pain tolerance so it was quite shocking.

Now I understand why women scream during sex, it’s because they’re screaming in pain, but if I love him then I’ll have to get on with it, that’s the point of sex, I’m willing to go through pain to pleasure him. putting up with pain is a normal part of being a woman. I feel bad for even asking this question..
