Inner critic body stress response

Hi the program is helping me and I did manage to have sex last week after several months. I need to understand whether I have a pelvic floor issue. My inner critic seems to trigger a lower back/bladder area discomfort tension if I stress about sex. I have also had bouts of chronic non bacterial prostatitis throughout my life. Reverse keagals seem to be helping more than pelvic floor squeezes ? Any advice similar issues the community can share ?
