Sex feels different now?

Using the pill reduces testosterone in your body, which in turn can mean that your body doesnt' produce as much natural lubrication and you don't have the same sex drive. The combination means pain with sex. You're probably tight because with sexual excitement, your vagina expands and lengthens temporarily as it becomes engorged with fluid. That didn't happen in your case, or not as much in your case, which means problems. Was he hitting your cervix? Yes, you certainly should use extra lube. Clearly you do not have enough lubrication, you didn't have enough even when you were not on the pill, which is why a lubricated condom wasn't adequate. So regardless of what else you do, use more lube to prevent being sore. Then, get off the pill--it will probably fix most of these issues. But it will take your body a few months to adjust when you stop the pill, so give it 3 or 4 months to see improvement.
