Well, I agree with the previous post in that you shouldn't rush her. BUT, if she really, really, really, really, really wants to have intercourse, I think she's going to have to try to bear the pain enough for you to get fully in. Has the hymen been broken? If it hasn't been, she's going to have pain until it is. It's no picnic, but in my opinion, it's better to get that part over with quick. If the hymen has been broken and she's still having pain, she may need to see a doctor.
