Pain after sex

I've been dating someone new for about 6 months now... and its different. Like I'm not staying wet how I used to be.. and we can only do it once every couple days because my vagina hurts after. We use condoms and  I use a vibrator so I'm wet but I'm 26 I have NEVER in my life needed a fucking vibrator to be wet! 😳😩 Is this in any way normal? Or is there something wrong with my vagina. Side note I have been to the Dr for a check up and I'm all clear on the STD side.. she just said it's probably the rough sex.. but the sex doesn't seem rougher than previous partners.. and he's not the biggest out of them either. 😶
