Anyone feel this during ovulation? Or after

My hubby and I did some amazing baby dancing last night. First off let me say, not gloating but anyways he's an amazing size like just below the huge radar. My problem is we were first going at it and every time he put it in, it was extremely painful. Like there was no room. Usually she will stretch for him and I'm all good but she wouldn't budge last night. Anyone know what this might mean? Or what it is?
